General Description
The LM4860 is a bridge-connected audio power amplifier capable of delivering 1W of continuous average
power to an 8Ohm load with less than 1% THD+N over the audio spectrum from 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 LM4860 does not require
output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power
portable systems.
The LM4860 features an externally controlled, low-power consumption shutdown mode, as well as an internal
thermal shutdown protection mechanism. It also includes two headphone control inputs and a headphone
sense output for external monitoring.
The unity-gain stable LM4860 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.
