AD7401A - Isolated Sigma-Delta Modulator
The AD7401A1 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 AD7401A operates from a 5 V power supply and accepts a differential input sign
