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
