AD210BNATI 3-Port Isolation Amplifier, 2500V rms Isolation, 120dB CMR, DIP

The AD210BNATI is a high voltage, wide-bandwidth three-port isolation amplifier designed for applications where input signals must be measured, processed, or transmitted without a galvanic connection. It isolates the input, output, and power ports in a compact DIP package.

This isolation amplifier is an upgraded drop-in replacement for AD210BN and is designed for long-term production support. It is suitable for multichannel data acquisition, current shunt measurements, process signal isolation, high voltage instrumentation, and other isolated signal measurement applications.

The AD210BNATI achieves both signal and power isolation through internal transformer coupling. This eliminates the need for an external isolated DC-DC converter, helping reduce circuit complexity, board space, component count, and overall system cost.

Powered from a single 15 V DC supply, the AD210BNATI delivers high accuracy, wide 500 kHz bandwidth, low gain drift, and isolated power for both the input and output ports. It also includes an uncommitted input amplifier for added design flexibility.

The true three-port architecture lets the AD210BNATI serve as either an input or output isolator. It breaks ground loops and leakage paths while rejecting common-mode voltage and noise, maintaining accurate signal reproduction even under sustained common-mode stress.
