OPA637 - OPERATIONAL AMPLIFIERS

Download the OPA637 datasheet PDF. This datasheet also covers the OPA627_Burr variant, as both devices belong to the same operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The OPA627 and OPA637 Difet operational amplifiers provide a new level of performance in a precision FET op amp.

When compared to the popular OPA111 op amp, the OPA627/637 has lower noise, lower offset voltage, and much higher speed.

Key Features

  • q VERY LOW NOISE: 4.5nV/√Hz at 10kHz q FAST.
