The LM4861M/NOPB is a bridge-connected 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 was 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.
No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary
