PA3332 Datasheet



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.

* Including de-pop circuit
* Output power at 1% THD+N, VDD=5V
