Audio Amp Speaker 2-CH Stereo 3.2W Class-AB 20-Pin TSSOP EP T/R, LM4866MTEX/NOPB, Texas Instruments

Описание

The LM4866 is a bridge-connected (BTL) stereo audio power amplifier which, when connected to a 5V supply, delivers 2.2W to a 4O load or 2.5W to a 3O load with less than 1.0% THD+N (see Notes below).With the LM4866 packaged in the WQFN, the customer benefits include low thermal impedance, low profile, and small size. This package minimizes PCB area and maximizes output power.The LM4866 features an externally controlled, low-power consumption 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 to use few external components and provide high quality output power in a surface mount package.Note: An LM4866PWP or LM4866NHW that has been properly mounted to a circuit board will deliver 2.2W into 4?. The other package options for the LM4866 will deliver 1.1W into 8?. See thesections for further information concerning the LM4866PWP and LM4866NHW.Note: An LM4866PWP or LM4866NHW that has been properly mounted to a circuit board will deliver 2.5W into 3?.
