LM4836 - Texas Instruments

LM4836 Stereo 2W Audio Power Amplifier

The LM4836 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω with less than 1.0% THD+N, or 2.2W into 3Ω with less than 1.0% THD+N (see Notes below). Boomer audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amo.
