5. TPA3008D2
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
Ω . 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-output shorts. A fault
terminal allows short-circuit fault reporting and automatic recovery. Thermal protection ensures that
the maximum junction temperature is not exceeded.
