Analog DevicesEVAL-CN0194-SDPZ

EVAL-CN0194-SDPZ is Galvanically Isolated, 2-Channel, 16-Bit, Simultaneous Sampling, Daisy-Chained Data Acquisition System evaluation Board.

This circuit provides galvanic isolation for high speed, high accuracy, simultaneous sampling analog-todigital conversion applications. The 16-bit AD7685PulSAR 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 ±10 V industrial signal to match the input requirements of the ADC. The flexible circuit includes a precision ADR391 reference and two quadchannel ADuM1402 digital isolators to provide a compact and cost effective solution to a popular industrial data acquisition application.

• Simultaneous sampling
• Isolated high speed analog to digital conversion
• Level shift and attenuates +/- 10 V industrial signal
