LM4878

1 Watt Audio Power Amplifier in micro SMD package

with Shutdown Logic Low

General Description

The LM4878 is a bridge-connected audio power amplifier

capable of delivering 1 W of continuous average power to an

8Ω load with less than .2% (THD) from a 5V power supply.

Key Specifications

Power Output at 0.2% THD

1 W (typ)

Shutdown Current

0.01 µA (typ)

Boomer audio power amplifiers were designed specifically to

provide high quality output power with a minimal amount of

external components. Since the LM4878 does not require

output coupling capacitors or bootstrap capacitors. It is op-

timally suited for low-power portable applications.

Features

n Internal pulldown resistor on shutdown.

n micro SMD package (see App. note AN-1112)

n 5V - 2V operation

n No output coupling capacitors or bootstrap capacitors.

n Unity-gain stable

The LM4878 features an externally controlled, low-power

consumption shutdown mode, as well as an internal thermal

shutdown protection mechanism.

n External gain configuration capability

The unity-gain stable LM4878 can be configured by external

gain-setting resistors.

Applications

n Cellular Phones

n Portable Computers

n Low Voltage Audio Systems

Typical Application

10136001
