LM4889 Product details

Description

The LM4889 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

Features

a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with a logic low. Additionally, the LM4889 features an internal thermal shutdown protection mechanism. The LM4889 contains advanced pop & click circuitry to eliminate noise which would otherwise occur during turn-on and turn-off transitions. The LM4889 is unity-gain stable and can be configured by external gain-setting resistors. Key Specifications j Improved PSRR at 217Hz, 5 - 3.3V j Power Output at 5.0V & 2%.
