LM4899 - 1Watt Fully Differential Audio Power Amplifier

Description

The LM4899 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 either logic high or low depending on mode selection. Driving the shutdown mode pin either high or low enables the shutdown select pin to be driven in a likewise manner to enable Shutdown. Additionally, the LM4899 features an internal thermal shutdown protection mechanism. The LM4899 contains advanced pop & click circuitry which virtually eliminates noises which would otherwise occur during turn-on and turn-off.
