GENERAL DESCRIPTION
The AD8200 is a single-supply difference amplifier for amplifying
and low-pass filtering small differential voltages in the presence of
a large common-mode voltage. The input CMV range extends
from –2 V to +24 V at a typical supply voltage of 5 V.
The AD8200 is offered in die and packaged form. Both package
options are specified over wide temperature ranges, making the
AD8200 well suited for use in many automotive platforms. The
SOIC package is specified over a temperature range of –40°C to
+125°C. The die is specified from –40°C to +150°C.

OUTPUT
Automotive platforms demand precision components for better
system control. The AD8200 provides excellent ac and dc per-
formance that keeps errors to a minimum in the user’s system.
Typical offset and gain drift in the SOIC package are 6 µV/°C
and 10 ppm/°C, respectively. The device also delivers a mini-
mum CMRR of 80 dB from dc to 10 kHz.
The AD8200 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 20.
