The 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 available in die and packaged form. The MSOP and SOIC packages are specified over a wide temperature range, from −40°C to +125°C, making the AD8202 well-suited for use in many automotive platforms.
Automotive platforms demand precision components for better system control. The AD8202 provides excellent ac and dc performance keeping errors to a minimum in the user’s system. Typical offset and gain drift in the SOIC package are 0.3 µV/°C and 1 ppm/°C, respectively. Typical offset and gain drift in the MSOP package are 2 µV/°C and 1 ppm/°C, respec¬tively. The device also delivers a minimum CMRR of 80 dB from dc to 10 kHz.
The AD8202 features an externally accessible 100 kΩ resistor at the output of the Preamp A1 that can be used for low-pass filter applications and for establishing gains other than 20.
