DESCRIPTION

Efficient Class-D Operation Eliminates Need

for Heat Sinks

The TPA3124D2 is a 15-W (per channel), efficient,

class-D audio power amplifier for driving stereo

speakers in a single-ended configuration; or, a mono

•

Four Selectable, Fixed-Gain Settings

Internal Oscillator (No External Components

Required)

speaker in

a bridge-tied-load configuration. The

TPA3124D2 can drive stereo speakers as low as 4 Ω.

The efficiency of the TPA3124D2 eliminates the need

for an external heat sink when playing music.

•

Single-Ended Analog Inputs

Thermal and Short-Circuit Protection With

Auto Recovery

The gain of the amplifier is controlled by two gain

select pins. The gain selections are 20, 26, 32, and

36 dB.

•

Space-Saving Surface Mount 24-Pin TSSOP

Package

The patented start-up and shutdown sequences

minimize pop noise in the speakers without additional

circuitry.
