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 V/°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 k resistor at
the output of the preamplifier (A1), which can be used for low-
pass filtering and for establishing gains other than 20.
