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
鈩?
The high efficiency of the
TPA3100D2, 92%, 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.
