AD7400 Datasheet (Analog Devices) - Isolated Sigma-Delta Modulator

AD7400, Isolated Sigma-Delta Modulator

The AD7400 is a second-order, sigma-delta (Σ-Δ) modulator that converts an analog input signal to a high speed, 1-bit data stream with on-chip digital isolation based on Analog Devices, Inc.

iCoupler® technology.

The AD7400 operates from a 5 V power supply and accepts a differential input signal of
