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
