OPA637 Overview
Description
The OPA627 and OPA637 (OPA6x7) operational amplifiers (op amps) provide a new level of performance in a precision FET operational amplifier. When compared to the popular OPA111 op amp, the OPA6x7 have lower noise, lower offset voltage, and higher speed.
Key Features
- Very low noise: 4.5nV/√Hz at 10kHz
- Fast settling time: – OPA627: 550ns to 0.01% – OPA637: 450ns to 0.01%
- Low VOS: 100µV maximum
- Low drift: 0.8µV/°C maximum
- Low IB: 5pA maximum
- Gain options: – OPA627: Unity-gain stable – OPA637: Stable in gain ≥ 5
