15-W Stereo Class-D Audio Power Amplifier (TPA3107) - TPA3107D2

Next Generation 15-W, Stereo, Analog Input Class-D Audio Amplifier:  TPA3110D2

Next Generation 30-W, Stereo Class-D Amplifier with Low-Idle Power Dissipation (Analog-In) for Battery Operated Systems Available:  TPA3128D2


The TPA3107D2 is a 15-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. The TPA3107D2 can drive stereo speakers as low as 6 . The high efficiency of the TPA3107D2, 87%, 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 outputs are fully protected against shorts to GND, VCC, and output-to-output shorts with an auto recovery feature and monitor output.
