GENERAL DESCRIPTION
The AD8203 is a single-supply difference amplifier for amplify-
ing 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.
The AD8203 is available in packaged form. The MSOP and
SOIC packages are specified over a wide temperature range,
from 40°C to +125°C, making the AD8203 well-suited for use
in many automotive platforms.
Automotive platforms demand precision components for better
system control. The AD8203 provides excellent ac and dc
performance keeping errors to a minimum in the user’s system.
Typical offset and gain drift in the SOIC package are 0.3 V/°C and
1 ppm/°C, respectively. Typical offset and gain drift in the MSOP
package are 2 μV/°C and 1 ppm/°C, respectively. The device also
delivers a minimum CMRR of 80 dB from dc to 10 kHz.
The AD8203 features an externally accessible 100 k resistor at
the output of the Preamp A1, which can be used for low-pass
filter applications and for establishing gains other than 14.
