General Description
LM4866 General Description
The LM4866 is a bridge-connected (BTL) stereo audiopower amplifier which, when connected to a 5V supply,delivers 2.2W to a 4Ω load (Note 1) or 2.5W to a 3Ω load(Note 2) with less than 1.0% THD+N.
With the LM4866 packaged in the LLP, the customer benefitsinclude low thermal impedance, low profile, and small size.This package minimizes PCB area and maximizes outputpower.
The LM4866 features an externally controlled, low-powerconsumption shutdown mode, and thermal shutdown protection.It also utilizes circuitry to reduce "clicks and pops"during device turn-on.
Boomer audio power amplifiers are designed specifically touse few external components and provide high quality outputpower in a surface mount package.
