TPA3123D2 Overview
The TPA3123D2 is a 25-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 TPA3123D2 can drive stereo speakers as low as 4 Ω. The efficiency of the TPA3123D2 eliminates the need for an external heat sink when playing music.
