DESCRIPTION

The TPA3005D2 is a 6-W (per channel) efficient,

Class-D audio amplifier for driving bridged-tied stereo

speakers. The TPA3005D2 can drive stereo speakers

as low as 8 Ω. The high efficiency of the TPA3005D2

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. Thermal

protection ensures the maximum junction

temperature is not exceeded.
