LM4923 Product details

Description

The LM4923 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

Features

a low-power consumption shutdown mode. To facilitate this, Shutdown may be enabled by logic low. Additionally, the LM4923 features an internal thermal shutdown protection mechanism. The LM4923 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.
