产品概述
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.The LM4861 features an externally controlled, low-power consumption shutdown mode, as
well as an internal thermal shutdown protection mechanism.The unity-gain stable LM4861 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.
