OPA1637 Datasheet Audio Operational Amplifier

Manufacturer: Texas Instruments

Overview: .ti. OPA1637 SBOSA00B – DECEMBER 2019 – REVISED AUOGPUAST12603270 SBOSA00B – DECEMBER 2019 – REVISED AUGUST 2020 OPA1637 High-Fidelity, Low-Noise, Fully-Differential, Burr-Brown™ 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.

The OPA1637 also converts single-ended sources to differential outputs required by high-fidelity analog-todigital converters (ADCs).

Designed for exceptional low noise and THD, the bipolar super-beta inputs yield a very low noise figure at very-low quiescent current and input bias current.

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.
