LM4866

2.2W Stereo Audio Amplifier

General 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 (Note 1) or 2.5W to a 3Ω load

(Note 2) with less than 1.0% THD+N.

Key Specifications

n P_Oat 1% THD+N

LM4866LQ, 3Ω, 4Ω loads

LM4866MTE, 3Ω, 4Ω loads

LM4866MTE, 8Ω load

LM4866MT, 8Ω load

2.5W(typ), 2.2W(typ)

1.1W(typ)

With the LM4866 packaged in the LLP, the customer benefits

include low thermal impedance, low profile, and small size.

This package minimizes PCB area and maximizes output

power.

1.1W(typ)

0.7µA(typ)

2.0V to 5.5V

n Shutdown current

n Supply voltage range

The LM4866 features an externally controlled, low-power

consumption shutdown mode, and thermal shutdown protec-

tion. It also utilizes circuitry to reduce “clicks and pops”

during device turn-on.

Features

n Stereo BTL amplifier mode

n “Click and pop” suppression circuitry

n Unity-gain stable

Boomer audio power amplifiers are designed specifically to

use few external components and provide high quality output

power in a surface mount package.

n Thermal shutdown protection circuitry

n TSSOP and Exposed-DAP LLP packages

Note 1: An LM4866MTE or LM4866LQ 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 Information sections

for further information concerning the LM4866MTE and LM4866LQ.

Applications

n Multimedia monitors

n Portable and desktop computers

n Portable televisions

Note 2: An LM4866MTE or LM4866LQ that has been properly mounted to a

circuit board will deliver 2.5W into 3Ω.

Typical Application

20018601

Note: Pin out shown for LLP package. Refer to the Connection Diagrams for the pinout of the TSSOP package.
