Product Summary

The TPA3120D2PWP is a 25W (per channel) efficient, Class-D audio power amplifier for driving stereo speakers in a single-ended configuration or a mono bridge-tied speaker. The TPA3120D2PWP can drive stereo speakers as low as 4W. The efficiency of the TPA3120D2PWP eliminates the need for an external heat sink when playing music.
