LM4820-6 - Fixed Gain 1Watt Audio Power Amplifier

Description

The LM4820-6 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 logic low. Additionally, the LM4820-6 features an internal thermal shutdown protection mechanism. The LM4820-6 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.
