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 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.
FEATURES
* Including de-pop circuit
* Output power at 1% THD+N, VDD=5V
2.0W/CH (TYP.) into a 4Load
1.3W/CH (TYP.) into a 8Load
* Output power at 10% THD+N, VDD=5V
2.6W/CH (typical) into a 4Load
1.6W/CH (typical) into a 8Load
* BTL mode (Bridge-Tied Load)
* Maximum output power clamping circuitry contained
* Mute and shutdown control available
* Stereo input MUX

DESCRIPTION
Ground connection for circuitry, directly connected to thermal pad.
Embedded test mode pin, please keep it floating.
Left channel + output in BTL mode
Left channel IN1 input, selected when IN1 /IN2 pin is held low.
Left channel IN2 input, selected when IN1 /IN2 pin is held high.
Connect to voltage divider for left channel internal mid-supply bias.
Supply voltage input for left channel and for primary bias circuits.
Shutdown mode control signal input, places entire IC in shutdown mode when held
high, IDD< 5µA.
Left channel - output in BTL mode.
Mode control signal input, hold low for activation, hold high for mute.
Right channel - output in BTL mode
MUX control input, hold high to select in2 inputs (5,20), hold low to select in1 inputs
(4,21).
Ground connection for circuitry.
Supply voltage input for right channel.
Connect to voltage divider for right channel internal mid-supply bias.
Right channel in2 input, selected when IN1 /IN2 pin is held high.
Right channel in1 input, selected when IN1 /IN2 pin is held low.
Right channel + output in BTL mode
The output power can be clamped by setting a low bound voltage to this pin. The high
bound voltage will be generated internally. The output voltage will be clamped between
high/low bound voltages. Then the output power is lim-ited. It is weakly pull-low
internally, let this pin floating or tied to GND can deactivate this function.
Recommend connecting the Thermal Pad to the GND for excellent power dissipation.
