LM4927 Product details

Description

The LM4927 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 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 and turn-off transitions. Key Specifications j Improved PSRR at 217Hz j Power Output at 5.0V @ 10% THD (4Ω) j Power Output at 3.3V @ 1% THD j Shutdown Current 85dB (typ) 2.5W (typ) 550mW (typ) 0.1µA.
