AD777x Customer Evaluation Board User Guide
The EVAL-AD7770-ARDZ / EVAL-AD7771-ARDZ / EVAL-AD7779-ARDZ evaluation kit features the AD7770, AD7771, and AD7779 24-bit, analog-to-digital converters (ADCs). The board interfaces with the system demonstration platform SDP-K1 controller board (EVAL-SDP-CK1Z), with the DE10-Nano development kit and with any microcontroller supported by Mbed platform via Arduino interface. The controller board can supply power to the EVAL-AD7770-ARDZ/EVAL-AD7771-ARDZ/EVAL-AD7779-ARDZ evaluation board and also connects to a PC running a Windows® operating system via a USB cable.
The AD777x evaluation software fully configures the AD7770, AD7771, and AD7779 device register functionality and provides dc and ac time domain analysis in the form of waveform graphs, histograms, and associated noise analysis for ADC performance evaluation.
This kit allows the user to evaluate the features of the ADC. The user PC software executable controls the AD7770, AD7771, and AD7779 over the USB cable through the controller board.
Full specifications for the AD7770, AD7771, or AD7779 are available in the AD7770, AD7771, or AD7779 data sheets and should be consulted in conjunction with this user guide when working with the evaluation board
The AD777x Family
The AD777x is an 8-channel, simultaneous sampling analog-to-digital converter (ADC). Eight full Σ-Δ ADCs are on-chip. The AD777x provides an ultralow input current to allow direct sensor connection. Each input channel has a programmable gain stage allowing gains of 1, 2, 4, and 8 to map lower amplitude sensor outputs into the full-scale ADC input range, maximizing the dynamic range of the signal chain.
Each channel contains an ADC modulator and a sinc3/sinc5 (AD7770 and AD7779 just sinc3), low latency digital filter. A sample rate converter (SRC) is provided to allow fine resolution control over the AD777x output data rate (ODR). This control can be used in applications where the ODR resolution is required to maintain coherency with 0.01 Hz changes in the line frequency.
The SRC is programmable through the serial port interface (SPI). The AD777x implements two different interfaces: a data output interface and SPI control interface. The ADC data output interface is dedicated to transmitting the ADC conversion results from the AD777x to the processor. The SPI writes to and reads from the AD777x configuration registers and for the control and reading of data from the successive approximation register (SAR) ADC. The SPI can also be configured to output the Σ-Δ conversion data.
The AD777x includes a 12-bit SAR ADC. This ADC can be used for AD777x diagnostics without having to decommission one of the Σ-Δ ADC channels dedicated to system measurement functions. With the use of an external multiplexer, which can be controlled through the three general-purpose input/output pins (GPIOs), and signal conditioning, the SAR ADC can validate the Σ-Δ ADC measurements in applications where functional safety is required. In addition, the AD777x SAR ADC includes an internal multiplexer to sense internal nodes.

Schematic
Top Level
The top level is formed by the interconnection of all different blocks: Power supplies, Analog filter, reference, ADC and the interface.
The input power for the EVAL is either externally supplied by P9 or by the host connected with the Arduino interface. This voltage is internally used in the “POWERSUPPLIES” block to generate AVDD and IOVDD.
P7 and P8 are used to generate externally AVDD and IOVDD and supply the ADC.
Jumpers P33, P34, P35, P36 and P37 are used to short AVSSx to GND when Unipolar supply is used and thereby reduce the noise in the different ground layers.
Power Supplies
The AD777x family requires up to 5 different supply voltages which can be easily configured thanks to jumpers and the switch S1 available in the EVAL.
When the default configuration is used, the ADC supply voltages are internally generated with 3 LDOS. The LDOS are connected to the outputs of a dual DC-to-DC Switching Regulator which generates two intermediate voltage -4V and 4V. The usage of LDOs help reducing the noise injected to the ADC.
IOVDD can be selected with P13. The internal 3.3V LDO is used by default. Two other options can be configured: VIO coming from the Arduino host or an external IOVDD connected to the connector P8.
The AD777x can be operated in bipolar or unipolar mode. When S1 is in position 1-2 and 4-5, AVSS and AVDD are configured in bipolar mode. In bipolar mode U4 will generate 1.65V and AVSSx is connected to the output of JP1, which will be either -1.65V (U5) or the voltage externally connected to P7.4.
When S1 is in position 3-2 and 6-5 the ADC is configured in unipolar mode and therefore AVSSX is grounded and AVDDx is either the external voltage connected to P7.1, P7.2 and P.7.3 or the 3.3V generated by U4.
To provide some flexibility to the user, several different analog filter configurations can be found in the evaluation board. The default resistor values are 0Ohm,and the capacitors are nor populated so no filter is implemented to the input signal.
Analog input signals are connected to P11 and P12 but channels CH0, CH1, CH2 and CH3 also have a second SMB connector in case a more precise measurements are required.
CH1 and CH2 are an example of a real protection circuit for noisy industrial environments where bidirectional TVS and protection diodes are necessary for ESD protection.
If R175 and R176 are removed, CH7 can be used together AMC-ADAxxxx-2ARMZ (Amplifier Mezzanine Card for ADC Drivers) to test the performance of the ADC with different input filter. The AMC can support any of Analog Devices operational amplifiers and ADC drivers in different packages. The user can configure the ADC driver as a Sallen-Key low-pass, high-pass, or band-pass filter, as a multiple feedback low-pass, high-pass, or band-pass filter, or as an inverting and noninverting operational amplifier. The user can also configure the AMC to drive a single-ended, fully differential, or a single-ended signal to a differential ADC.
VCM and Reference
This block is the responsible for the generation of the ADC reference and the common mode voltage.
Depending on the resistor mounted (R102, R101 or R103) the ADC reference voltage can be supplied by an discrete reference (R102), by the ADC itself (R101) or by a buffer connected to the output of the reference mentioned before (R103). Furthermore, two connector are provided (J10 and P20) just in case an external reference is desired.
The default Reference IC used in the EVAL is the LTC665LNBHMS8-2.5 but it is also possible to replace this reference with LTC6658BHMS8-2.5 or with ADR441ARMZ in which case the proper components must be mounted.
P19 is used to select the ADC common mode voltage. There are two option: connect the common mode voltage directly to the ADC's output VCM or use a intermediate buffer.
Interface
The AD777x communicates with the host via SPI. There are four primary signals: CS, SCLK, SDI, and SDO/RDY (all are inputs, except for SDO/RDY, which is an output).
Serial communication options

The readout values are sent to the host either via SPI commands of via DOUTx channels. Due to the limited number of readout values that a uC can process, the Zio extension has been added which allows some uC to use the audio SAI input interface to enhance the number of readout samples.
Since there exist two types of Board using the Zio extension, some resistors has been added to configure the SAI interface depending on the board selected. The resistors need to be mounted accordingly.
The EEPROM is only used for the Host to identify which EVAL has been plugged.
AD777x
The AD777x has multiple possible configurations and the following list will try to summarize how to configure it correctly with the existing hardware:
Clock:4 different clock sources can be used depending on the resistors mounted: Crystal, CMOS, EXT_MCLK from Arduino interface or connector J13.
SPI/ PIN control mode can be configured via JP7 (FORMAT1) and JP8 (FORMAT0). If both jumpers are set high, the device is configured in
SPI control mode, otherwise pin control mode.
P22, P23, P25 and P26, are used to configured the decimation rate and the number of channels in pin control mode. In
SPI mode control P23, P25 and P25 can cause a conflict with the configuration of the pins if they are configured as an output, so care must be taken with the jumper position. P22 in
SPI control must be in position 1-2 since this pin will behave as an error flag.
JP6 is used for the host as an error flag either in
SPI or pin control mode
R129 must be mounted if the SRC update is done via GPIO0 instead being done via
SPI commands.
R135 and R136 must be mounted depending on the selected mode to set properly the ALER/CS pin: R136 mounted to used the pin as
SPI chip selec; R135 to use the pin as error flag in pin control mode.
With resistors R137, R138 and R139 can be selected the MCLK divider in pin control mode. In
SPI control mode only R137 must be assembled to function as SDI pin.
With resistors R140, R141 and R142 can be selected the MCLK divider in pin control mode. In
SPI control mode only R140 must be assembled to function as
SCLK pin.
With resistors R172, R173 and R174 can be selected the MCLK divider in pin control mode. In
SPI control mode only R172 must be assembled to function as SDO pin.
JP9 is used for the clock source type selection: high for CMOS and low for Csytal.
P27 together with JP7 and JP8 is used in pin control mode for the output data format selection. In
SPI control mode P27 should be connected to position 1-2. In this case CONVST_SAR works as start for SAR conversion.

All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection.
Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.

Setting up the hardware (DE10-Nan)
You will need to:
-
Insert the Micro-
SD into the Micro-
SD Interface Connector (J11).
Connect the AD777x-ARDZ to the DE10Nano FPGA using the Arduino shield connection.
Connect
USB UART J4 (Micro
USB) to your host PC.
Plug your ethernet cable into the RJ45 ethernet connector(J10).
Plug the Power Supply into 5V Power input connector (J14) (DO NOT turn the device on).
Set the jumpers as seen in the below picture:
Turn it on.
Wait ~30 seconds for the “DONE” LED to turn blue.
All the products described on this page include ESD (electrostatic discharge) sensitive devices. Electrostatic charges as high as 4000V readily accumulate on the human body or test equipment and can discharge without detection.
Although the boards feature ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. This includes removing static charge on external equipment, cables, or antennas before connecting to the device.

Reference HDL Design
Functional Overview
The reference design is a processor based (ARM) embedded system. A functional block diagram of the system is given below.
The device interface is a self-contained peripheral similar to other such pcores in the system. The core is programmable through an AXI-lite interface.
