LM4858

Mono 1.5 W / Stereo 300mW Power Amplifier

General Description

Key Specifications

n Output Power at 1% THD+N, 1kHz:

The LM4858 is an audio power amplifier capable of deliver-

ing 1.5W (typ) of continuous average power into a mono 4Ω

bridged-tied load (BTL) with 1% THD+N or 95mW per chan-

nel of continuous average power into stereo 32Ω single-

ended (SE) loads with 1% THD+N, using a 5V power supply.

95mW (typ)

1% (typ)

The LM4858 can automatically switch between mono BTL

and stereo SE modes utilizing a headphone sense pin. It is

ideal for any system that provides both a monaural speaker

output and a stereo line or headphone output

n THD+N at 1kHz, 95mW into 32Ω SE

n Single Supply Operation

n Shutdown Current

2.4 to 5.5V

18µA (typ)

Boomer audio power amplifiers were designed specifically to

provide high quality output power with a minimal amount of

external components. Since the LM4858 does not require

bootstrap capacitors or snubber networks, it is optimally

suited for low-power portable systems.

Features

n Mono 1.5W BTL or stereo 300mW output

n Logic controlled headphone sense

n “Click and pop” suppression circuitry

n No bootstrap capacitors required

n Thermal shutdown protection

n Unity-gain stable

The LM4858 features an externally controlled, micropower

consumption shutdown mode and thermal shutdown protec-

tion. The unity-gain stable LM4858’s gain is set by external

gain-setting resistors

n Available in space-saving MSOP and LLP packaging

Applications

n Portable computers

n Desktop computers

n PDA’s

n Handheld games
