DESCRIPTION

The TPA3125D2 is a 10-W (per channel), efficient,

class-D audio power amplifier for driving stereo

speakers in a single-ended configuration; or, a mono speaker in a bridge-tied-load configuration. The

TPA3125D2 can drive stereo speakers as low as 4 Ω.

The efficiency of the TPA3125D2 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.

The patented start-up and shutdown sequences

minimize pop noise in the speakers without additional

circuitry.

The thru-hole package allows placement on

single-sided printed circuit boards.
