 ===== Power Supplies ===== ===== Power Supplies =====
-The evaluation board receives power through the EVAL-SDP board when connected to the PC via USB.  +By default, the board is powered from the USB. The board can be also powered from the J4 connector by setting LK3 to Position A or from Arduino standard headers 
-  * Linear regulators generate the required power supply levels from the applied VIN rail.  +The [[adi>en/products/Adum6411.html|ADuM6411]] isoPower® digital isolator is used to isolate power and data lines up to 2.5 kV rms.
-  * Each supply is decoupled at the point where it enters the board and again at the point where it connects to each device.+
  
-==== AVDD==== 
-  - **3.3V** supplied by ADP1720-3.3 (LK15, Pos A)(LK18, Pos A)

 ===== Serial Interface ===== ===== Serial Interface =====
 The evaluation board connects via the serial peripheral interface (SPI) to the Blackfin® [[adi>en/products/adsp-bf527.html|ADSP-BF527]] on the SDP-B board. The evaluation board connects via the serial peripheral interface (SPI) to the Blackfin® [[adi>en/products/adsp-bf527.html|ADSP-BF527]] on the SDP-B board.
 There are four primary signals: CS, SCLK, DIN, and DOUT/RDY (all are inputs, except for DOUT/RDY, which is an output). There are four primary signals: CS, SCLK, DIN, and DOUT/RDY (all are inputs, except for DOUT/RDY, which is an output).
-To operate the evaluation board in standalone mode, the AD7124 serial interface lines can be disconnected from the 120-pin header by removing the links LK21-24. The pins from these links can then be used to fly-wire the signals to an alternative digital capture setup.+The EVAL-AD4116ASDZ evaluation board connects to any microcontroller board that uses the Arduino standard headers. This can be developed user code in for a variety of platforms.  
 + 
 +To operate the evaluation board in standalone mode, disconnect any board connected, J9 can be used to access all SPI signals and set the input/output voltage levels.

 +===== Analog Inputs =====
 +Eleven voltage inputs are available on P1 to P3. 
 +If a different common voltage must be set for single-ended measurement, remove LK2 and connect the desired voltage to VINCOM on P2.
 +Five additional low-level inputs are available on P4. The differential voltage for these inputs is ±VREF only. 
  
 ===== Reference Options ===== ===== Reference Options =====
  
-The EVAL-AD7124-8SDZ includes an external 2.5 V reference (the ADR4525) and an internal 2.5 V reference. The default operation is to use the external reference input, which is set to accept the 2.5 V ADR4525 on the evaluation board. +The EVAL-AD4116ASDZ includes an external 2.5 V reference, the ADR4525ARZ. By default, LK1 is inserted, connecting the external reference to REF+ of the AD4116.  
-The reference used for a conversion is selected by choosing the reference in the Config registers associated with Setup 0 to Setup 7.  Switch between using the internal reference and external reference by accessing the AD7124-8 registers through the pop-ups via the evaluation software. Figure 1 (below) shows how to select the reference source for Setup 0 to Setup 7. Figure 2 shows the ADC_Control register setting that enables the internal reference.+Remove LK1 if using a different single-ended external reference. 
 +In the evaluation software, click the blue pop-up button associated with Setup 0 to Setup 7 to select the reference used for conversions by the AD4116. The pop-up button is located below the external reference controls in the block diagram (Label 7 in Figure 16).
