 The [[ADI>AD7689]] 16-bit, 8-channel, 250 kSPS PulSAR ADC contains all the necessary components for the multichannel low power data acquisition system. It includes a 16-bit SAR ADC, an 8-channel low crosstalk multiplexer, a low drift reference and buffer, a temperature sensor, a selectable one-pole filter, and a channel sequencer. The sequencer is useful for continuously scanning channels, and a microcontroller or FPGA is not required to control channel switching.
-The [[ADI>AD8605]] and [[ADI>AD8608]] are low cost single and quad rail-to-rail input and output CMOS amplifiers. The [[ADI>AD8608]] inverts, level shifts, and attenuates the ±10 V input signal so that it matches the input range of the ADC, which is 0 V to +4.096 V when using a +4.096 V reference and a +5 V single supply. The [[ADI>AD8605]] acts as an external reference buffer to provide sufficient driving ability for level shifting.

The [[ADI>AD8605]] acts as an external reference buffer to provide sufficient driving ability for level shifting. Both feature very low offset voltage, low input voltage and current noise, and wide signal bandwidth, therefore making them good choices for a wide variety of applications.
 The [[ADI>ADuM3471]] is a quad-channel digital isolator with an integrated PWM controller and transformer driver for an isolated dc-to-dc converter. It provides the isolated 5 V, 2 W power for the circuit as well as isolates the digital signals at the SPI interface.
 The EVAL-CN0254-SDPZ board connects to ADI’s System Demonstration Platform (SDP) and is powered by a 6 V power supply.
