LM4858 Product details

Description

The LM4858 is an audio power amplifier capable of delivering 1.5W (typ) of continuous average power into a mono 4Ω bridged-tied load (BTL) with 1% THD+N or 95mW per channel of continuous average power into stereo 32Ω singleended (SE) loads with 1% THD+N, using a 5V power supply.

Features

an externally controlled, micropower consumption shutdown mode and thermal shutdown protection. The unity-gain stable LM4858’s gain is set by external gain-setting resistors Key Specifications n n n n n n n n n n Output Power at 1% THD+N, 1kHz: LM4858LD 3Ω BTL LM4858LD 4Ω BTL LM4858MM 4Ω BTL LM4858MM,LD 8Ω BTL LM4858MM,LD 8Ω SE LM4858MM,LD 32Ω SE THD+N at 1kHz, 95mW into 32Ω SE Single Supply Operation Shutdown Current 1.9W (typ) 1.7W (typ) 1.5W (typ) 1.1W (typ) 300mW (typ) 95mW (typ) 1% (typ) 2.
