GENERAL DESCRIPTION
The AD8253 is an instrumentation amplifier with digitally programmable gains that has GΩ input impedance, low output noise, and low distortion making it suitable for interfacing with sensors and driving high sample rate analog-to-digital converters (ADCs). It has high bandwidth of 10 MHz, low THD and fast settling time of 615 ns to 0.001%. Offset drift and gain drift are specified to 1.2 μV/°C and 10 ppm/°C, respectively for G = 1000. In addition to its wide in……
