OPA1637 - Audio Operational Amplifier

General Description

The OPA1637 is a low-noise, low total harmonic distortion (THD), fully differential, Burr-Brown™ Audio operational amplifier that easily filters and drives fully differential, audio signal chains.

Key Features

  • Low input voltage noise: 3.7 nV/√Hz at 1 kHz.
  • Low THD + N:.
  • 120 dB at 1 kHz.
  • Low supply current: 950 µA at ±18 V.
  • Input offset voltage: ±200 µV (maximum).
  • Input bias current: 2 nA (maximum).
  • Low bias current noise: 400 fA/√Hz at 10 Hz.
  • Gain-bandwidth product: 9.2 MHz.
  • Differential output slew rate: 15 V/µs.
  • Wide input and output common-mode range.
  • Wide single-supply operating range: 3 V to 36 V.
