LM4876

1.1W Audio Power Amplifier with Shutdown Logic Low

General Description

Key Specifications

The LM4876 is a bridge-connected audio power amplifier ca-

pable of delivering typically 1.1W of continuous average

n THD at 1 kHz at 1W continuous

average output power into 8Ω

0.5 (max)

power to an 8Ω load with 0.5 (THD) from a 5V power sup-

n Output power at 10 THD+N

ply.

1.5W (typ)

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 LM4876 does not require

output coupling capacitors, bootstrap capacitors, or snubber

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

tems.

n Shutdown Current

0.01 µA (typ)

Features

n No output coupling capacitors, bootstrap capacitors, or

snubber circuits are necessary

n Small Outline packaging

n Unity-gain stable

The LM4876 features an externally controlled, low-power

consumption shutdown mode, which is achieved by driving

pin 1 with logic low. Additionally, the LM4876 features an in-

ternal thermal shutdown protection mechanism.

n External gain configuration capability

n Pin compatible with LM4861 and LM4871

The LM4876 is unity-gain stable and can be configured by

external gain-setting resistors.

Applications

n Mobile Phones

n Portable Computers

n Desktop Computers

n Low Voltage Audio Systems
