LM4863

Dual 2.2W Audio Amplifier Plus Stereo

Headphone Function

Check for Samples: LM4863

FEATURES

APPLICATIONS

•

Stereo Headphone Amplifier Mode

“Click and Pop” Suppression Circuitry

Unity-Gain Stable

•

Multimedia Monitors

•

Portable and Desktop Computers

Portable Televisions

Thermal Shutdown Protection Circuitry

DESCRIPTION

SOIC, TSSOP, exposed-DAP TSSOP, and

WQFN packages

The LM4863 is a dual bridge-connected audio power

amplifier which, when connected to a 5V supply, will

deliver 2.2W to a 4Ω load or 2.5W to a 3Ω load with

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

addition, the headphone input pin allows the

amplifiers to operate in single-ended mode when

driving stereo headphones.

KEY SPECIFICATIONS

•

PO at 1% THD+N

–

LM4863LQ, 3Ω, 4Ω loads: 2.5W(typ),

2.2W(typ)

Boomer audio power amplifiers were designed

specifically to provide high quality output power from

a surface mount package while requiring few external

components. To simplify audio system design, the

LM4863 combines dual bridge speaker amplifiers and

stereo headphone amplifiers on one chip.

–

LM4863MTE, 3Ω, 4Ω loads: 2.5W(typ),

2.2W(typ)

–

LM4863MTE, 8Ω load: 1.1W(typ)

LM4863, 8Ω: 1.1W(typ)

•

Single-ended mode THD+N at 75mW into 32Ω:

0.5%(max)

The LM4863 features an externally controlled, low-

•

Shutdown current: 0.7μA(typ)

power consumption shutdown mode,

stereo

headphone amplifier mode, and thermal shutdown

protection. It also utilizes circuitry to reduce “clicks

and pops” during device turn-on.

Supply voltage range: 2.0V to 5.5V

NOTE

An LM4863MTE or LM4863LQ that has been properly mounted to a circuit board will

deliver 2.2W into 4Ω. The other package options for the LM4863 will deliver 1.1W into 8Ω.

See Application Information for further information concerning the LM4863MTE and

LM4863LQ.

NOTE

An LM4863MTE or LM4863LQ that has been properly mounted to a circuit board and

forced-air cooled will deliver 2.5W into 3Ω.
