LM4861M

TEXAS INSTRUMENTS  LM4861M  音频功率放大器, 1通道, 0.5 W, 2V 至 5.5V, SOIC, 8 引脚

The is a 1.1W Audio Amplifier with shutdown mode. This Boomer series audio power amplifier capable of delivering 1.1W of continuous average power to an 8R load with 1% THD+N using a 5V power supply. Boomer audio power amplifier 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. This amplifier features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable can be configured by external gain-setting resistors for differential gains of up to 10 without the use of external compensation components. Higher gains may be achieved with suitable compensation.
