The AD8203 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 -6 V to +30 V at a typical supply voltage of 5 V. The AD8203 is available in die and packaged for use in a variety of applications, such as transmission control, diesel injection control, engine management, adaptive suspension control, and vehicle dynamics control.
The AD8203 is a single‑supply difference amplifier designed for amplifying and low‑pass filtering small differential voltages in the presence of a large common‑mode voltage. It operates over a wide temperature range and offers high common‑mode voltage capability, making it suitable for automotive applications such as transmission control and engine management.
