AD8251 - Programmable Gain Instrumentation Amplifier

Description

The AD8251 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).

Features

  • Small package: 10-lead MSOP Programmable gains: 1, 2, 4, 8 Digital or pin-programmable gain setting Wide supply: ±5 V to ±15 V Excellent dc performance High CMRR: 98 dB (minimum), G = 8 Low gain drift: 10 ppm/°C (maximum) Low offset drift: 1.8 μV/°C (maximum), G = 8 Excellent ac performance Fast settling time: 785 ns to 0.001% (maximum) High slew rate: 20 V/μs (minimum) Low distortion:.
  • 110 dB THD at 1 kHz, 10 V swing High CMRR over frequency: 80 dB to 50 kHz (minimum) Low noise: 18 nV/√.
