General Description

The ADuM7701 is a high performance, second-order, Σ-Δ modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology.

The device operates from a 4.5 V to 5.5 V power supply range (VDD1) and accepts a pseudo differential input signal of ±250 mV (±320 mV full-scale).

The pseudo differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.
