GENERAL DESCRIPTION

The AD8209 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 AD8209 is qualified per AEC-Q100 specifications. The

amplifier offers enhanced input overvoltage and ESD protection,

and includes EMI filtering.

performance, minimizing errors in the application. Typical offset

and gain drift in the MSOP package 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 AD8209 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 14.

Automotive applications demand robust, precision components for

improved system control. The AD8209 provides excellent ac and dc
