LM4992, 420mW Stereo Cell Phone Audio Amplifier

The LM4992 is a stereo audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

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

LM4992 Features

* independent shutdown control for each channel and a low-power consumption shutdown mode, which is achieved by driving both shutdown pins with logic low. Additionally, the LM4992 features an internal thermal shutdown protection mechanism. The LM4992 contains advanced pop & click circuitry which elimi
