Audio Power Amplifier

Monolithic IC MM3111

Outline

This IC is an audio power amp that can operate at low voltage. Operating supply voltage supports 3V and 5V

power amp, making it ideal for applications such as mobile phones and other portable communication

devices. It is equipped with the capability to provide continuous supply of 1W (Ave) output against 8Ω load

from a 5V single power supply with 2% high harmonic distortion (THD+N). MM3111 does not require an

output coupling capacitor, so that applications can be configured with the minimum number of external parts.

It also includes a shutdown function and can operate with low power consumption when a mute signal is

inputted into the SHUTDOWN pin. It also includes a thermal runaway protection function (thermal shutdown)

to allow a gain to be set with an external resistor.
