The EVAL-CN0194-SDPZ is an evaluation board described in the circuit from lab CN-0194, entitled "Galvanically isolated, 2-channel, 16bit, simultaneous sampling, daisy chained data acquisition system". This circuit provides galvanic isolation for high speed, high accuracy, simultaneous sampling analog to digital conversion applications. The 16bit AD7685 PulSAR ADC is versatile and allows monitoring of multiple channels through daisy chaining. An input circuit based on the AD8615 op amp level shifts, attenuates, and buffers a ±10V industrial signal to match the input requirements of the ADC. The flexible circuit includes a precision ADR391 reference and two quad channel ADuM1402 digital isolators to provide a compact and cost effective solution to a popular industrial data acquisition application.
