Additional preview pages of the LM4674 datasheet.

The LM4674 is a single supply, high efficiency, 2.5W/ channel, filterless switching audio amplifier.

high efficiency compared to conventional Class AB amplifiers. When driving and 8Ω speaker from a 3.6V supply, the device features 85% efficiency at PO = 500mW. Four gain options are pin selectable through the GAIN0 and GAIN1 pins. Output short circuit protection prevents the device from being damaged during fault conditions. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. Independent left/right shutdown controls maximizes power savings in mi.
