AD210 is a cost-effective and high-performance isolation amplifier with features including high CMV isolation, small size, wide bandwidth, low nonlinearity, and low gain drift. It is suitable for applications such as multichannel data acquisition, high voltage instrumentation amplifier, current shunt measurements, and process signal isolation.
The AD210 is a three‑port, wide‑bandwidth isolation amplifier offering up to 2500 V rms (continuous) common‑mode voltage and 120 dB CMR at a gain of 100 V/V. It is powered by a single +15 V supply and provides isolated +15 V at 5 mA on both input and output ports, eliminating the need for external DC‑DC converters.
The manual covers functional block diagrams, typical input configurations, adjustment circuits, PCB layout recommendations for multichannel use, and detailed performance characteristics such as bandwidth, phase shift, noise, and power‑supply behavior. Application examples include data‑acquisition isolation, current‑source circuits, and thermocouple amplification.
