AD8202 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages in the presence of a large common-mode voltage (CMV). The input CMV range extends from −8 V to +28 V at a typical supply voltage of 5 V. The AD8202 is a low-power, high-precision, single-supply difference amplifier that is particularly suited for automotive applications.
The AD8202 is a single‑supply difference amplifier designed for high common‑mode voltage operation, suitable for automotive applications such as transmission control and engine management. It offers a typical system gain of 20, low voltage offset (+1 mV), and excellent CMRR (80 dB at 10 kHz).
The datasheet provides full electrical specifications, absolute maximum ratings, pin descriptions, and typical performance curves. It also includes ESD handling guidance and revision history for the product.
