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 die and packaged form. The MSOP
and SOIC packages are specified over a wide temperature range,
from 40°C to +125°C, while the die is specified over a wider
temperature range, from 40°C to +150°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 μV/°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 kΩ resistor at
the output of the Preamp A1, which can be used for low-pass
filter applications and for establishing gains other than 14.
