TPA3116 Stereo Amplifier

Some of the text files within the PDF file :

The TPA3116 is a stereo 50-W efficient, stereo digital amplifier power stage for driving 2 bridge-tied speakers or up to 100 W single parallel bridge-tied load. The TPA3116D2 can drive a speaker with an impedance as low as 3.2 Ω (4 Ω typical). The high efficiency of the TPA3116D2 allows for a small external heat sink in the 32p DAD package and can even run without a heat sink for music power.
