AD8208WHRZ-RL Datasheet PDF - ADI

●Product Details

●The AD8208 is a single-supply difference amplifier ideal for amplifying and low-pass filtering small differential voltages in the presence of a large common-mode voltage. The input common-mode voltage range extends from −2 V to +45 V at a single +5 V supply. The AD8208 is qualified per AEC-Q100 specifications. The amplifier offers enhanced input overvoltage and ESD protection, and includes EMI filtering.

●Automotive applications demand robust, precision components for improved system control. The AD8208 provides excellent ac and dc performance, minimizing errors in the application. Typical offset and gain drift are less than 5 µV/°C and 10 ppm/°C, respectively. The device also delivers a minimum CMRR of 80 dB from dc to 10 kHz.

●The AD8208 features an externally accessible 100 kΩ resistor at the output of the preamplifier (A1), which can be used for low-pass filtering and for establishing gains other than 20.
