AD7400A Datasheet Isolated Sigma-delta Modulator

Manufacturer: Analog Devices

Overview: Preliminary Technical Data Isolated Sigma-Delta Modulator AD7400A.

General Description

The AD7400A1 is a second-order, 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 AD7400A operates from a 5 V power supply and accepts a differential input signal of ±200 mV (±320 mV full scale).
