GENERAL DESCRIPTION

BATTERY

14V

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.

DEVICE

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.

POWER

DEVICE

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 ꢀV/°C and 1 ppm/°C, respectively. The device also

delivers a minimum CMRR of 80 dB from dc to 10 kHz.

DIODE

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.
