FEATURES
DESCRIPTION
2
• 6-W/Ch Into an 8-Ω Load From a 12-V Supply
• Up to 92% Efficient, Class-D Operation
The TPA3005D2 is a 6-W (per channel) efficient,
Class-D audio amplifier for driving bridged-tied stereo
Eliminates Need For Heatsinks
speakers. The TPA3005D2 can drive stereo speakers
• 8.5-V to 18-V Single-Supply Operation
as low as 8 Ω. The high efficiency of the TPA3005D2
• Four Selectable, Fixed Gain Settings
eliminates the need for external heatsinks when
• Differential Inputs Minimizes Common-Mode playing music.
Noise
The gain of the amplifier is controlled by two gain
• Space-Saving, Thermally Enhanced
select pins. The gain selections are 15.3, 21.2, 27.2,

and 31.8 dB.
• Thermal Protection and Short Circuit
The outputs are fully protected against shorts to
GND, VCC, and output-to-output shorts. Thermal
• Pinout Similar to TPA3002D2, TPA3003D2,
protection ensures the maximum junction
and TPA3004D2
temperature is not exceeded.
APPLICATIONS
• LCD Monitors and TVs
• All-In-One PCs
