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. In order to prevent the speakers

from burned-out, the UTC PA3332 also has a function of maximum

output power clamping is designed.
