AD7401 Datasheet (Analog Devices) - Isolated Sigma-Delta Modulator

AD7401, Isolated Sigma-Delta Modulator

The AD74011 is a second-order, sigma-delta (Σ-Δ) modulator that converts an analog input signal into a high speed, 1-bit data stream with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology.

The AD7401 operates from a 5 V power supply and accepts a differential input signal
