General Description

The OPA1622, dual, bipolar-input, SoundPlus™ audio operational amplifier achieves a very low, 2.8-nV/√Hz noise density with an ultralow THD+N of –119.2 dB at 1 kHz and drives a 32-Ω load at 100mW output power.

The OPA1622 offers extremelyhigh ac PSRR and CMRR specifications that eliminate noise from power supplies, making the OPA1622 ideal for use in portable-audio applications.

This device also has a high output-drive capability of +145 mA per –130 mA.
