General Description
The LM4861 is a bridge-connected audio power amplifier capable of delivering 1.1W of continuous average
power to an 8Ohm 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.
