DESCRIPTION
The TPA3106D1 is a 40-W efficient, Class-D audio
power amplifier for driving bridged-tied stereo
speakers. The TPA3106D1 can drive stereo speakers
as low as 4Ω. The high efficiency, ~92%, of the
TPA3106D1 eliminates the need for an external heat
sink when playing music.
The gain of the amplifier is controlled by two gain
select pins. The gain selections are 20, 26, 32, 36 dB.
The outputs are fully protected against shorts to
GND, V_CC, and output-to-output shorts with an auto
recovery feature and monitor output.
