The AD8214 is a fast response, high common-mode voltage, current shunt comparator. The device operates on the high side rail of any DC current sensing application, provided the voltage is between 5 V and 65 V.
The AD8214 is a high‑side current shunt comparator that operates from 5 V to 65 V supply voltage. It features a fast <100 ns input‑to‑output response, an internal 2.4 V regulator, and built‑in 10 mV hysteresis for reliable over‑current detection.
The device is supplied in an 8‑lead MSOP package, qualified for automotive use, and offers specifications such as 2 MΩ differential input impedance, ±30 nA input bias current, and output currents up to 1.2 mA. Detailed pin functions, performance curves, and application examples are provided in the datasheet.
