† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
DescriptionThe TPA3003D2 is a 3-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied stereo speakers. The TPA3003D2 can drive stereo speakers as low as 8 . The high efficiency of the TPA3003D2 eliminates the need for external heatsinks when playing music.Stereo speaker volume is controlled with a dc voltage applied to the volume control terminal offering a range of gain from 40 dB to 36 dB.
