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 externally accessible 100 k 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 excellent in the AD8202 data sheet. ac and dc performance, minimizing errors in the application.
