(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operations 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.




Description

The TPA3120D2 is a 25-W (per channel) efficient, Class-D audio power amplifier for driving stereo speakers in a single-ended configuration or a mono bridge-tied speaker. The TPA3120D2 can drive stereo speakers as low as 4 W. The efficiency of the TPA3120D2 eliminates the need for an external heat sink when playing music.The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB.The patented start-up and shut-down sequences minimize "pop" noise in the speakers without additional circuitry.
