LM4866
2.2W Stereo Audio Amplifier
Checkfor Samples: LM4866
1FEATURES DESCRIPTIONThe LM4866 isa bridge-connected (BTL) stereo
Stereo BTL Amplifier Mode audio power amplifier which, when connectedtoa 5V
• “Click and Pop” Suppression Circuitry supply, delivers 2.2Wtoa 4Ω loador 2.5Wtoa 3Ω
Unity-Gain Stable load with less than 1.0% THD+N (see Notes below).
Thermal Shutdown Protection Circuitry With the LM4866 packaged in the WQFN, the
TSSOP and Exposed-DAP WQFN Packages customer benefits include low thermal impedance,
low profile, and small size. This package minimizes
PCB area and maximizes output power.
KEY SPECIFICATIONSThe LM4866 features an externally controlled, low-
• POat 1% THD+Npower consumption shutdown mode, and thermal
– LM4866LQ, 3Ω load: 2.5W(typ) shutdown protection.It also utilizes circuitryto reduce
– LM4866LQ, 4Ω load: 2.2W(typ) “clicks and pops” during device turn-on.
LM4866MTE, 3Ω load: 2.5W(typ) Boomer audio power amplifiers are designed
– LM4866MTE, 4Ω load: 2.2W(typ) specifically to use few external components and
provide high quality output powerina surface mount
– LM4866MTE, 8Ω load: 1.1W(typ)package.
– LM4866MT, 8Ω load: 1.1W(typ)
Note: An LM4866PWP or LM4866NHW that has
• Shutdown current: 0.7μA(typ) been properly mountedtoa circuit board will deliver
• Supply voltage range: 2.0Vto 5.5V 2.2W into 4Ω. The other package options for the
LM4866 will deliver 1.1W into 8Ω. See the Application
APPLICATIONS Information sections for further information
concerning the LM4866PWP and LM4866NHW.
• Multimedia Monitors Portable and Desktop Computers Note: An LM4866PWP or LM4866NHW that has
been properly mountedtoa circuit board will deliver
• Portable Televisions 2.5W into 3Ω.
