ATIA202KY

Overview

The ATIA202KY is a high voltage isolation amplifier designed for applications requiring galvanic isolation between input and output stages. It features an uncommitted input op amp, isolated power outputs, and internal transformer coupling for signal transmission down to DC. The device operates from a single 15V supply, providing a bandwidth of 20kHz and a maximum nonlinearity of ±0.01%. It supports gain settings from 1V/V to 100V/V with high common-mode rejection ratios up to 130dB.

Feature Summary

• Provides total galvanic isolation between input and output stages using internal transformer coupling.
• Includes an uncommitted input operational amplifier for flexible circuit configurations.
• Delivers isolated power outputs to supply external loads or other components.
• Eliminates the need for external DC-DC converters, reducing design overhead.

Applications

• Multichannel data acquisition systems
• Current shunt measurements
• Motor controls
• Process signal isolation
• High voltage instrumentation amplifiers

Procurement Notes
