Product Summary

The LM4860MX is a bridge-connected audio power amplifier capable of delivering 1W of continuous average power to an 8W 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 LM4860MX does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The LM4860MX 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 1 to 10 without the use of external compensation components.
