OPA4277 Overview
The OPAx277 series of precision operational amplifiers replace the industry standard OP-177. The OPAx277 devices offer improved noise, wider output voltage swing, and are twice as fast with half the quiescent current.
OPA4277 Key Features
- Ultra-low offset voltage: 10 μV
- Ultra-low drift: ±0.1 μV/°C
- High open-loop gain: 134 dB
- High mon-mode rejection: 140 dB
- High power-supply rejection: 130 dB
- 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
