Beschreibung
- Circuit provides galvanic isolation for high speed, high accuracy, simultaneous sampling analog-to digital conversion applications. The 16-bit 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 ±10 V 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
