LM4866

2.2W Stereo Audio Amplifier

Check for Samples: LM4866

FEATURES

DESCRIPTION

The LM4866 is a bridge-connected (BTL) stereo

audio power amplifier which, when connected to a 5V

supply, delivers 2.2W to a 4Ω load or 2.5W to a 3Ω

load with less than 1.0% THD+N (see Notes below).

•

Stereo BTL Amplifier Mode

“Click and Pop” Suppression Circuitry

Unity-Gain Stable

Thermal Shutdown Protection Circuitry

TSSOP and Exposed-DAP WQFN Packages

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.

KEY SPECIFICATIONS

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.

LM4866LQ, 3Ω load: 2.5W(typ)

LM4866LQ, 4Ω load: 2.2W(typ)

LM4866MTE, 3Ω load: 2.5W(typ)

LM4866MTE, 4Ω load: 2.2W(typ)

LM4866MTE, 8Ω load: 1.1W(typ)

LM4866MT, 8Ω load: 1.1W(typ)

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 4Ω. The other package options for the

LM4866 will deliver 1.1W into 8Ω. See the Application

•

Shutdown current: 0.7μA(typ)

Supply voltage range: 2.0V to 5.5V
