High Common-Mode Voltage, Single-Supply Difference Amplifier

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 form. The MSOP and SOIC packages are specified over a wide temperature range, from -40°C to +125°C, while the die is specified over a wider temperature range, from -40°C to +150°C, making the AD8203 well-suited for use in many automotive platforms.
