GENERAL DESCRIPTION

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 for automotive applications. 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 in both the SOIC and MSOP packages 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.
