LM4861

1.1W Audio Power Amplifier with Shutdown Mode

General Description

Key Specifications

The LM4861 is a bridge-connected audio power amplifier ca-

pable of delivering 1.1W of continuous average power to an

8Ω load with 1% (THD) using a 5V power supply.

n THD at 1 kHz at 1W continuous

average output power into 8Ω

1.0% (max)

1.5W (typ)

0.6 µA (typ)

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 using surface mount packaging. Since

the LM4861 does not require output coupling capacitors,

bootstrap capacitors, or snubber networks, it is optimally

suited for low-power portable systems.

n Shutdown Current

Features

n No output coupling capacitors, bootstrap capacitors, or

snubber circuits are necessary

The LM4861 features an externally controlled, low-power

consumption shutdown mode, as well as an internal thermal

shutdown protection mechanism.

n Small Outline (SO) packaging

n Compatible with PC power supplies

n Thermal shutdown protection circuitry

n Unity-gain stable

The unity-gain stable LM4861 can be configured by external

gain-setting resistors.

n External Gain Configuration Capability

Applications

n Personal computers

n Portable consumer products

n Self-powered speakers

n Toys and games
