20-W STEREO CLASS-D AUDIO POWER AMPLIFIER

FEATURES

APPLICATIONS

•

Televisions

•

20-W/ch into an 8-Ω Load From a 18-V Supply

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

15-W/ch into an 4-Ω Load From a 12-V Supply

Operates from 10 V to 26 V

DESCRIPTION

The TPA3100D2 is a 20-W (per channel) efficient,

Class-D audio power amplifier for driving bridged-tied

stereo speakers. The TPA3100D2 can drive stereo

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

TPA3100D2, 92%, eliminates the need for an

external heat sink when playing music.

92% Efficient Class-D Operation Eliminates

Need for Heat Sinks

•

Four Selectable, Fixed Gain Settings

Differential Inputs

The gain of the amplifier is controlled by two gain

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

36 dB.

Thermal and Short-Circuit Protection With

Auto Recovery Feature

•

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.
