ISO224ADWVR Description

Short technical summary and product information.

The ISO224ADWVR from Texas Instruments is a precision isolated amplifier that separates input circuitry from the output via an isolation barrier. It is optimized for isolated voltage measurement in industrial applications, offering a ±12-V peak-to-peak input voltage range and a differential output range of ±4 V.

 

This amplifier boasts a reinforced isolation rating with a withstand isolation voltage of 5000 Vrms and a working isolation voltage of 1500 Vrms. It provides high Common-Mode Transient Immunity (CMTI), with a minimum of 15 kV/µs and a typical of 80 kV/µs for the ISO224B version. The device operates with a single supply on the high-side from 4.5 V to 18 V and on the low-side from 4.5 V to 5.5 V.

 

Key electrical characteristics include low DC error operation, with input offset voltage as low as ±5 mV at 25°C and an input offset drift of ±3 µV/°C (typical for ISO224B). Gain error is ±0.3% at 25°C and nonlinearity is ±0.01% maximum (for ISO224B).

 

The ISO224ADWVR is supplied in a SOIC package with dimensions of 5.85 mm x 11.5 mm. It is suitable for applications requiring robust isolation and precise voltage measurement.
