LM4927 2.5 Watt Fully Differential Audio Power Amplifier

The LM4927 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 2.5 watts of continuous average power to a 4Ω load with less than 10% distortion (THD+N) from a 5V.

LM4927 Features

* a low-power consumption shutdown mode. To facilitate this, Shutdown may be enabled by logic low. Additionally, the LM4927 features an internal thermal shutdown protection mechanism. The LM4927 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on
