Product details

Description

The LM4831 is a monolithic integrated circuit that provides a stereo three input mixer, two stereo input analog multiplexer, a stereo line out and a dual 1W bridged audio power amplifier.

Features

an externally controlled, low-power consumption shutdown mode, as well as both headphone and docking station modes. To temporarily override the shutdown mode and allow audio signals to be amplified, the LM4831 provides four “beep” pins.
