DESCRIPTION
The TPA3120D2 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 TPA3120D2 can drive
stereo speakers as low as 4
. The efficiency of the
TPA3120D2 eliminates the need for an external heat
sink when playing music.
