Product details

Description

The LM4904 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply.

Features

a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic high. Additionally, the LM4904 features an internal thermal shutdown protection mechanism. The LM4904 contains advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The LM4904 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications j Improved PSRR at 217Hz & 1KHz j Power Output at 5.0V, 1% T.
