AD202JYATI High Voltage Isolation Amplifier, AD202JY Replacement, 750V rms, SIP

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

Analog Devices discontinued the AD202 family in October 2022, with final shipments in October 2024, and named no replacement part and no pin-compatible alternative. The AD202JYATI is an upgraded drop-in replacement for the AD202JY: the pinout and footprint are unchanged, so no board modification is required. It is RoHS compliant, which the original part was not, and our datasheet guarantees production for at least ten years.

It suits multichannel data acquisition, current shunt measurement, motor control, process signal isolation and high voltage instrumentation, and other applications calling for isolated analog measurement.

The AD202JYATI achieves both signal and power isolation through internal transformer coupling, removing the external isolated DC-DC converter from the design and reducing board space, component count and overall system cost.

The AD202JYATI is powered from a single 15 V DC supply and provides isolated power outputs of ±7.5 V for the input amplifier, the modulator and a light external load. An uncommitted input operational amplifier allows buffering or gain to be added without extra parts.
