Product Summary
The TPA3124D2PWPR is a 15-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 TPA3124D2PWPR can drive stereo speakers as low as 4Ω. The efficiency of the TPA3124D2 eliminates the need for an external heat sink when playing music. The applications of the TPA3124D2PWPR include Flat Panel Televisions, DLP TVs, CRT TVs and Powered Speakers.
