The industry standard OP-177 has been replaced by the precision operational amplifiers of the OPA2277U series. They have better noise characteristics, a larger output voltage swing, and twice the speed with half the quiescent current. Ultralow offset voltage, drift, bias current, strong common-mode rejection, and power supply rejection are among the features. For optimum design flexibility, the single, dual, and quad models have identical specs.

• Low Bias Current: 1-nA maximum 

  
  

• Wide Supply Range: ±2 V to ±18 V

  
  

• Low Quiescent Current: 800 μA/amplifier

  
  

• Single, Dual, and Quad Versions

  
  

• Replaces OP-07, OP-77, and OP-177

  
  

• Ultralow Offset Voltage: 10 μV

  
  

• Ultralow Drift: ±0.1 μV/°C

  
  

• High Open-Loop Gain: 134 dB

  
  

• High Common-Mode Rejection: 140 dB

  
  

• High Power Supply Rejection: 130 dB
