LM4855 - Boomer AUDIO POWER AMPLIFIER

General Description

The LM4855 is an audio power amplifier system capable of delivering 1.1W (typ) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N and 115mW (typ) per channel of continuous average power into stereo 32Ω BTL loads with 0.5% THD+N, using a 5V power supply.

Key Features
