PA3332 - 2.6W STEREO AUDIO AMPLIFIER

General Description

The UTC PA3332 is a stereo audio power amplifier.

When the device is idle, it enters SHDN mode for some low current consumption applications.

The current dissipation is thus reduced below 5μA.

UNISONIC TECHNOLOGIES CO., LTD PA3332 Preliminary 2.6W STEREO AUDIO AMPLIFIER  DESCRIPTION The UTC PA3332 is a stereo audio power amplifier. When the device is idle, it enters SHDN mode for some low current consumption applications. The current dissipation is thus reduced below 5μA. Mute function is included to mute the output. Operating on a 5V power supply, the UTC PA3332 is capable of driving a 4.0 Ω BTL load at a continuous average RMS output of 2.0W per channel with a less than 1% THD.％ There are two input paths, therefore, two different gain loops can be set in the same PCB. We could choose one of the two gain paths through the logic level of IN/IN pin. This increases the flexibility of the hardware design.
