DESCRIPTION
The LM4936 is a monolithic integrated circuit that provides volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (1) with less than 1% THD or 2.2W into 3Ω (2) with less than 1% THD.
Boomer audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external ponents. The LM4936 incorporates a SPI or I2C...
