AD8203:  High Common-Mode Voltage, Single-Supply Difference Amplifier

Product Description

The AD8203 is a single-supply difference amplifier for amplifying 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.

Features

  • High common-mode voltage range -6 V to
    +30 V at a 5 V supply voltage
  • Operating temperature range -40°C to +125°C
  • Supply voltage range: 3.5 V to 12 V
  • Low-pass filter (1-pole or 2-pole)
  • Excellent ac and dc performance
    ±1 mV voltage offset (8-lead SOIC)
    ±1 ppm/°C typical gain drift
    80 dB CMRR minimum dc to 10 kHz
