LM4881

Dual 200 mW Headphone Amplifier with

Shutdown Mode

Check for Samples: LM4881

FEATURES

DESCRIPTION

The LM4881 is a dual audio power amplifier capable

of delivering 200mW of continuous average power

into an 8Ω load with 0.1% THD+N from a 5V power

supply.

•

VSSOP Surface Mount Packaging

Unity-gain Stable

•

External Gain Configuration Capability

Thermal Shutdown Protection Circuitry

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 LM4881 does

not require bootstrap capacitors or snubber networks,

it is optimally suited for low-power portable systems.

No Bootstrap Capacitors, or Snubber Circuits

are Necessary

APPLICATIONS

•

Headphone Amplifier

Personal Computers

Microphone Preamplifier

The LM4881 features an externally controlled, low

power consumption shutdown mode which is virtually

clickless and popless, as well as an internal thermal

shutdown protection mechanism.

KEY SPECIFICATIONS

The unity-gain stable LM4881 can be configured by

external gain-setting resistors.

•

THD+N at 1kHz at 125mW Continuous Average

Output Power into 8Ω 0.1% (max)

THD+N at 1kHz at 75mW Continuous

0.02% (typ)

Output Power at 10% THD+N at 1kHz into 8Ω

300 mW (typ)

•

Shutdown Current 0.7µA (typ)

Supply Voltage Range 2.7V to 5.5 V
