LM4861MX

LM4861 1.1W音频功率放大器关断模式 LM4861 1.1W Audio Power Amplifier with Shutdown Mode

DESCRIPON

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
