DESCRIPTION
Thanks to its compact and power-dissipation efficient QFN16 package with exposed pad, it suits a variety of applications. 3D effects enhancement is programmed through a two digital input pin interface that allows more flexibility on each output audio sound channel. 5 6 7 8 GND GND STBYR STBYL Each output channel (left and right), also has its own external controlled standby mode pin to reduce the supply current to less than 10nA per channel.
