LM4880

Dual 250 mW Audio Power Amplifier with

Shutdown Mode

Check for Samples: LM4880

FEATURES

DESCRIPTION

The LM4880 is a dual audio power amplifier capable

of delivering typically 250mW per channel of

continuous average power to an 8Ω load with 0.1%

THD+N using a 5V power supply.

•

No Bootstrap Capacitors or Snubber Circuits

are Necessary

•

Small Outline (SOIC) and PDIP Packaging

Unity-Gain Stable

Boomer audio power amplifiers were designed

specifically to provide high quality output power with a

minimal amount of external components using

surface mount packaging.

External Gain Configuration Capability

APPLICATIONS

•

Headphone Amplifier

Personal Computers

CD-ROM Players

Since the LM4880 does not require bootstrap

capacitors or snubber networks, it is optimally suited

for low-power portable systems.

The LM4880 features an externally controlled, low-

power consumption shutdown mode, as well as an

internal thermal shutdown protection mechanism.
