Product Summary

The TPA3123D2PWPR is a 25-W (per channel) efficient, Class-D audio power amplifier for driving stereo speakers in a single ended configuration or a mono bridge-tied speaker. The TPA3123D2PWPR can drive stereo speakers as low as 4Ω. The efficiency of the TPA3123D2 eliminates the need for an external heat sink when playing music.
