LM4861M-LM4861MX
1.1W Audio Power Amplifier with Shutdown Mode
LM4861
1.1W Audio Power Amplifier with Shutdown Mode
General Description

The LM4861isa bridge-connected audio power amplifier
capableof delivering 1.1Wof continuous average powerto8Ω load with 1% THD+N usinga5V power supply.
Boomer audio power amplifiers were designed specificallyto
provide high quality output power witha minimal amountof
external components using surface mount packaging. Since
the LM4861 does not require output coupling capacitors,
bootstrap capacitors,or snubber networks,itis optimally
suitedfor low-power portable systems.
The LM4861 featuresan externally controlled, low-power
consumption shutdown mode,as wellasan internal thermal
shutdown protection mechanism.
The unity-gain stable LM4861 canbe configuredby external
gain-setting resistorsfor differential gainsofupto10 without
the useof external compensation components. Higher gains
maybe achieved with suitable compensation.
Key Specifications
THD+Nfor 1kHzat 1W continuous
average output power into8Ω 1.0% (max) Output powerat 10% THD+N 1kHz into8Ω 1.5W (typ) Shutdown Current 0.6µA (typ)
Features
No output coupling capacitors, bootstrap capacitors,or
snubber circuits are necessary Small Outline (SO) packaging Compatible with PC power supplies Thermal shutdown protection circuitry Unity-gain stable External gain configuration capability
Applications
Personal computers Portable consumer products Self-powered speakers Toys and games
