LM4840 Stereo 2W Audio Power Amplifiers with Digital Volume Control and Input Mux
General Description
The LM4840 is a monolithic integrated circuit that provides digital volume control and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (Note 1) with less than 1.0% THD or 2.2W into 3Ω (Note 2) with less than 1.0% THD. Boomer ® audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external components. The LM4840 incorporates a digital volume control, stereo bridged audio power amplifiers, an input mux, and a last volume level memory function to save the volume setting during shutdown.
