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)
