Product Overview
ISO224ADWVR from TI is a precision isolated amplifier with 5000Vrms isolation. +/-12V input range. 150kHz bandwidth. 0.3% gain accuracy. SOIC-16 with capacitive isolation.
Working Principle
Capacitive isolation barrier separates input and output. Delta-sigma modulator digitizes input, transfers across barrier, reconstructs as analog output. 5000Vrms isolation. +/-12V input range. 0.3% gain accuracy. 150kHz bandwidth.
