The AD8202-KGD is a single-supply difference amplifier ideal Typical offset and gain drift are 5 µV/°C and 1 ppm/°C respect- for amplifying and low-pass filtering small differential voltages tively. The device also delivers a minimum CMRR of 80 dB from in the presence of a large common-mode voltage. The input dc to 10 kHz. common-mode voltage range extends from −8 V to +28 V at a The AD8202-KGD features an external y accessible 100 kΩ resistor single +5 V supply. The AD8202-KGD is qualified for automotive at the output of the preamplifier (A1), which can be used for low- applications. pass filtering and for establishing gains other than 20. Automotive applications demand robust, precision components Additional application and technical information can be found for improved system control. The AD8202-KGD provides excel ent in the AD8202 data sheet. ac and dc performance, minimizing errors in the application.
