LM4862

675 mW Audio Power Amplifier with Shutdown Mode

General Description

Key Specifications

The LM4862 is a bridge-connected audio power amplifier ca-

pable of delivering typically 675 mW of continuous average

power to an 8Ω load with 1% (THD) from a 5V power supply.

n THD at 500 mW continuous average

output power at 1 kHz into 8Ω

1% (max)

n Output power at 10% THD+N at

1 kHz into 8Ω

Boomer audio power amplifiers were designed specifically to

provide high quality output power with a minimal amount of

external components. Since the LM4862 does not require

output coupling capacitors, bootstrap capacitors, or snubber

networks, it is optimally suited for low-power portable sys-

tems.

825 mW (typ)

0.7 µA (typ)

n Shutdown Current

Features

n No output coupling capacitors, bootstrap capacitors or

snubber circuits are necessary

n Small Outline or DIP packaging

n Unity-gain stable

n External gain configuration capability

n Pin compatible with LM4861

The LM4862 features an externally controlled, low-power

consumption shutdown mode, as well as an internal thermal

shutdown protection mechanism.

The unity-gain stable LM4862 can be configured by external

gain-setting resistors.

Applications

n Portable Computers

n Cellular Phones

n Toys and Games
