LM4861 Datasheet PDF

●DESCRIPTION

●The LM4861 is a bridge-connected audio power amplifier capable of delivering 1.1W of continuous average power to an 8Ω load with 1% THD+N using a 5V power supply.

●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 LM4861 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optimally suited for low-power portable systems.

●FEATURES

●• No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary

●• Small Outline (SOIC) 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

●KEY SPECIFICATIONS

●• THD+N for 1kHz at 1W continuous average output power into 8Ω 1.0% (max)

●• Output power at 10% THD+N at 1kHz into 8Ω 1.5 W (typ)

●• Shutdown Current 0.6µA (typ)
