AD8203,pdf datasheet (Differen

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.
