AD202JYATI High Voltage Isolation Amplifier, 1000V Peak Isolation, 130dB CMR, SIP

The AD202JYATI is a high voltage isolation amplifier designed for applications where input signals must be measured, processed, or transmitted without a galvanic connection. It provides signal isolation and isolated power in a compact SIP package.

This isolation amplifier is an upgraded drop-in replacement for AD202JY and is designed for long-term production support. It is suitable for multichannel data acquisition, current shunt measurements, motor controls, process signal isolation, high voltage instrumentation, and other isolated signal measurement applications.

The AD202JYATI uses internal transformer coupling to provide total galvanic isolation between the input and output stages. This eliminates the need for an external isolated DC-DC converter, helping reduce circuit complexity, board space, component count, and overall system cost.

Powered directly from a 15 V DC supply, the AD202JYATI features high accuracy, wide bandwidth, low power operation, flexible input configuration, and isolated power outputs. It also includes an uncommitted input amplifier for added design flexibility.

The AD202JYATI uses an amplitude modulation technique to allow transformer coupling of signals down to DC. Its internal power transformer provides isolated power for the input amplifier, modulator, and external load, making it well suited for precision isolated analog signal acquisition.
