GENERAL DESCRIPTION

The AD8203 is a single-supply difference amplifier for amplifying and low-pass filtering small differential voltages in the presence of a large common-mode voltage (CMV). The input CMV range extends from −6 V to +30 V at a typical supply voltage of 5 V.

FEATURES

−6 V to +30 V at a 5 V supply voltage

Operating temperature range: −40°C to +125°C

Supply voltage range: 3.5 V to 12 V

Low-pass filter (1-pole or 2-pole)

Excellent ac and dc performance

±1 mV voltage offset (8-lead SOIC)

±1 ppm/°C typical gain drift

80 dB CMRR minimum dc to 10 kHz

APPLICATIONS

Transmission control
