TPA3122D2 (ACTIVE)

15-W Stereo Class-D Audio Power Amplifier with SE Outputs (TPA3122)

 

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

Description

The TPA3122D2 is a 15-W (per channel) efficient, Class-D audio power amplifier for driving stereo single ended speakers or mono bridge tied load. The TPA3122D2 can drive stereo speakers as low as 4. The efficiency of the TPA3122D2 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, and 36 dB.
