Speaker amplifier from New Japan Radio

NJU72065 is a 1.2W mono speaker amplifier with electronic volume control function that fits in applications with voice command and beep sound.

A special standby function gives it a low energy consumption when on mute. It also reduces pop noise when it's activated, as well on standby mode. All functions are controlled by I²C interface. Download datasheet here.
