LM4876

1.1W Audio Power Amplifier with Logic Low

Shutdown

Check for Samples: LM4876

FEATURES

DESCRIPTION

The LM4876 is a single 5V supply bridge-connected

audio power amplifier capable of delivering 1.1W (typ)

of continuous average power to an 8Ω load with 0.5%

THD+N.

•

Does Not Require Output Coupling Capacitors,

Bootstrap Capacitors, Or Snubber Circuits

•

10-pin VSSOP and 8-pin SOIC Packages

Unity-Gain Stable

Like other audio amplifiers in the Boomer series, the

LM4876 is designed specifically to provide high

quality output power with a minimal amount of

external components. The LM4876 does not require

output coupling capacitors, bootstrap capacitors, or

snubber networks. It is perfectly suited for low-power

portable systems.

External Gain Set

APPLICATIONS

•

Mobile Phones

Portable Computers

Desktop Computers

Low-Voltage Audio Systems

The LM4876 features an active low externally

controlled, micro-power shutdown mode. Additionally,

the LM4876 features an internal thermal shutdown

protection mechanism. For PCB space efficiency, the

LM4876 is available in VSSOP and SOIC surface

mount packages.

KEY SPECIFICATIONS

•

THD+N at 1kHz for 1W Continuous Average

Output Power into 8Ω 0.5% (max)

The unity-gain stable LM4876's closed loop gain is

set using external resistors.

•

Output Power At 1kHz Into 8Ω with 10%

THD+N 1.5 W (typ)

•

Shutdown Current 0.01µA (typ)

Supply Voltage Range 2.0V to 5.5 V
