DESCRIPTION
The TPA3008D2 is a 10-W (per channel) efficient,
class-D audio amplifier for driving bridged-tied stereo
speakers. The TPA3008D2 can drive stereo speakers
as low as 8
鈩?
The high efficiency of the TPA3008D2
eliminates the need for external heatsinks when
playing music.
The gain of the amplifier is controlled by two gain
select pins. The gain selections are 15.3, 21.2, 27.2,
and 31.8 dB.
The outputs are fully protected against shorts to
GND, VCC, and output-to-output shorts. A fault ter-
minal allows short-circuit fault reporting and automatic
recovery. Thermal protection ensures that the maxi-
mum junction temperature is not exceeded.
