15-W STEREO CLASS-D AUDIO POWER AMPLIFIER

FEATURES

APPLICATIONS

•

Televisions

•

10-W/ch into an 4-Ω Load From a 17-V Supply

15-W/ch into an 8-Ω Load From a 28-V Supply

Operates from 10 V to 30 V

•

DESCRIPTION

The TPA3122D2 is a 15-W (per channel) efficient,

Class-D audio power amplifier for driving stereo

single ended speakers or mono bridge tied load. The

TPA3122D2 can drive stereo speakers as low as 4Ω.

The efficiency of the TPA3122D2 eliminates the need

for an external heat sink when playing music.

Efficient Class-D Operation

Four Selectable, Fixed Gain Settings

Internal Oscillator (No External Components

Required)

•

Single Ended Analog Inputs

The gain of the amplifier is controlled by two gain

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

36 dB.

Thermal and Short-Circuit Protection with

Auto Recovery Feature
