OPA637 - High-Speed JFET Operational Amplifiers

Download the OPA637 datasheet PDF. This datasheet also covers the OPA627 variant, as both devices belong to the same high-speed jfet operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General 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 2.
