High Precision Operational Amplifiers

Recommended alternative parts

  • OPA2188  - The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent.   OPA2188 has improved Vos and drift
  • OPA2227  -  Dual version of OPA227 which features low noise 3nV/sqrt(Hz), offset voltage 75µV, open-loop-gain 160dB and CMRR 138dB
  • OPA177  -  Features offset voltage 25µV, open-loop-gain 130dB and low drift 0.3µV/°C. OPA277 upgrade for the OPA177
  • OPA627  -  Features low noise 4.5nV/sqrt(Hz) at 10kHz and low drift 0.8µV/°C max
  • OPA27  -  OPA227 upgrade for OP-27
  • OPA227  -  Single version of OPA2227 which features low noise 3nV/sqrt(Hz), offset voltage 75µV, open-loop-gain of 160dB and CMRR 138dB
