The AD8210 is a single-supply, difference amplifier ideal for high voltage, bidirectional current shunt monitor applications.
The AD8210 is a single‑supply difference amplifier designed for amplifying small differential voltages in the presence of large common‑mode voltages. It operates from a 5 V supply and supports an input common‑mode range of –2 V to +65 V, making it suitable for high‑voltage current‑sensing applications such as motor control and vehicle dynamics.
The device offers a buffered output with 5 mA drive capability, ratiometric half‑scale offset adjustment (0.05 V to 4.9 V), and excellent AC/DC performance over a –40 °C to +125 °C temperature range. Key specifications include 20 V/V gain, ±0.5 % gain accuracy at 25 °C, 20 ppm/°C gain drift, and a 4000 V HBM ESD rating.
