10-W STEREO CLASS-D AUDIO POWER AMPLIFIER

FEATURES

APPLICATIONS

•

Televisions

•

10-W/ch into an 8-Ω Load From a 13-V Supply

9.2-W/ch into an 8-Ω Load From a 12-V Supply

Operates from 10 V to 26 V

DESCRIPTION

The TPA3101D2 is a 10-W (per channel) efficient,

Class-D audio power amplifier for driving bridged-tied

stereo speakers. The TPA3101D2 can drive stereo

speakers as low as 4 Ω. The high efficiency of the

TPA3101D2, 87%, eliminates the need for an

external heat sink when playing music.

87% Efficient Class-D Operation Eliminates

Need for Heat Sinks

•

Four Selectable, Fixed Gain Settings

Differential Inputs

Thermal and Short-Circuit Protection With

Auto Recovery Feature

The gain of the amplifier is controlled by two gain

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

36 dB.

•

Clock Output for Synchronization With

Multiple Class-D Devices

The outputs are fully protected against shorts to

GND, V_CC, and output-to-output shorts with an auto

recovery feature and monitor output.
