OPA2328 - CMOS Operational Amplifiers

Download the OPA2328 datasheet PDF. This datasheet also covers the OPA328 variant, as both devices belong to the same cmos operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The single-channel OPA328 and dual-channel OPA2328 (OPAx328) are a new generation family of precision, low-voltage CMOS operational amplifiers optimized for very low noise and wide bandwidth.

Key Features

  • Precision with zero-crossover distortion:.
  • Low offset voltage: 50µV (maximum).
  • High CMRR: 120dB.
  • Rail-to-rail I/O.
  • Wide bandwidth: 40MHz.
  • Low input bias current: 1pA (maximum).
  • Low noise: 6.1nV/√Hz at 10kHz.
  • Slew rate: 30V/µs.
  • Fast 0.01% settling time: 180ns.
  • Single-supply voltage range: 2.2V to 5.5V.
  • Unity-gain stable 2.
