Product details

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.

Features

a 32 step digital volume control eight distinct output modes. The digital volume control output modes are programmed through a three-wire serial control interface, that allows flexibility in routing mixing audio channels. and and SPI and Key Specifications n THD+N at 1kHz, 1.1W into 8Ω BTL n THD+N at 1kHz, 115mW into 32Ω BTL n Single Supply Operation 1.0% (typ) 0.5% (typ) 2.6 to 5.0V Features n n n n n n n n 1.1W (typ) output power with 8Ω mono BTL load 115mW (typ) output power with stereo 32Ω.
