20-W STEREO CLASS-D AUDIO POWER AMPLIFIER

FEATURES

APPLICATIONS

•

Televisions

•

Qualified for Automotive Applications

•

20 W/Channel Into an 8-Ω Load From

an 18-V Supply

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.

•

10 W/Channel Into an 8-Ω Load From

a 12-V Supply

15 W/Channel Into an 4-Ω Load From

a 12-V Supply

•

Operates From 10 V to 26 V

92% Efficient Class-D Operation Eliminates

Need for Heat Sinks

The gain of the amplifier is controlled by two gain

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

32 dB, or 36 dB.

•

Four Selectable Fixed-Gain Settings

Differential Inputs

The outputs are fully protected against shorts to

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

auto-recovery feature and monitor output.

Thermal and Short-Circuit Protection With

Auto-Recovery Feature

•

Clock Output for Synchronization With

Multiple Class-D Devices
