GENERAL DESCRIPTION
The AD8228 is a high performance instrumentation amplifier with very high gain accuracy. Because all gain setting resistors are internal and laser trimmed, gain accuracy and gain drift are better than can be achieved with typical instrumentation amplifiers.

FEATURES

Pin strappable gains of 10 and 100
Wide power supply range: ±2.3 V to ±18 V
DC specifications (B Grade, G = 10)
  2 ppm/°C gain drift
  0.02% gain error
  50 μV maximum input offset voltage
  0.8 μV/°C maximum input offset drift
  0.6 nA maximum input bias current
  100 dB CMRR
AC specifications
  650 kHz, –3 dB bandwidth (G = 10)
  2 V/μs slew rate
Low noise
  8 nV/√Hz, @ 1 kHz (G = 100)
  0.3 μV p-p from 0.1 Hz to 10 Hz (G = 100)
