Product introduction

The TPA3121D2 features a 15W stereo Class-D audio power amplifier with SE output

illustrate

The TPA3121D2 is a 15-watt (per channel), high-efficiency, Class D audio power amplifier for driving mono speakers in single-ended configurations or stereo speakers in a bridged load configuration. The TPA3121D2 can drive as few as 4 stereo speakers 。 The TPA3121D2 efficiency eliminates the need for an external heatsink when playing music.

Two gain select pins for the amplifier's gain control. Gain options are 20, 26, 32 and 36 dB.

Patented start-up and shutdown without the need for additional circuitry sequences in the smallest speaker popular noise.
