LM4928 - 1.2 Watt Stereo Fully Differential Audio Amplifier

General Description

The LM4928 is an stereo fully differential stereo audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication devices.

Key Features

  • a low-power consumption shutdown mode. To facilitate this, shutdown may be enabled by logic low. Additionally, the LM4928 features an internal thermal shutdown protection mechanism. The LM4928 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.
