OPA1664 - Audio Operational Amplifier

Download the OPA1664 datasheet PDF. This datasheet also covers the OPA1662 variant, as both devices belong to the same audio operational amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

The dual OPA1662 and quad OPA1664 (OPA166x) series of bipolar-input SoundPlus™ audio operational amplifiers achieve a low 3.3nV/√Hz noise density with an ultra-low distortion of 0.00006% at 1kHz.

Key Features

  • Low noise: 3.3nV/√Hz at 1kHz.
  • Low distortion: 0.00006% at 1kHz.
  • Low quiescent current: 1.5mA per channel.
  • Slew rate: 17V/μs.
  • Wide gain bandwidth: 22MHz (G = +1).
  • Unity gain stable.
  • Rail-to-rail output.
  • Wide supply range: ±1.5V to ±18V or 3V to 36V.
  • Dual and quad versions available.
  • Small package sizes: Dual: SOIC-8 and VSSOP-8 Quad: SOIC-14 and TSSOP-14 2.
