LM4862

675 mW Audio Power Amplifier with Shutdown

Mode

Check for Samples: LM4862

FEATURES

DESCRIPTION

The LM4862 is a bridge-connected audio power

amplifier capable of delivering typically 675mW of

continuous average power to an 8Ω load with 1%

THD+N from a 5V power supply.

•

No Output Coupling Capacitors, Bootstrap

Capacitors or Snubber Circuits are Necessary

•

Small Outline or 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. Since the

LM4862 does not require output coupling capacitors,

bootstrap capacitors, or snubber networks, it is

optimally suited for low-power portable systems.

External Gain Configuration Capability

Pin Compatible with LM4861

APPLICATIONS

•

Portable Computers

Cellular Phones

The LM4862 features an externally controlled, low-

power consumption shutdown mode, as well as an

internal thermal shutdown protection mechanism.

Toys and Games

The unity-gain stable LM4862 can be configured by

external gain-setting resistors.

KEY SPECIFICATIONS

THD+N for 500mW Continuous Average

Output Power at 1kHz into 8Ω 1% (max)

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

825 mW (typ)

Shutdown Current 0.7μA (typ)
