AD52060-2x20W Stereo Class-D Audio Amplifier


AD52060-2x20W Stereo Class-D Audio Amplifier with Power Limit DataSheet

Description
The AD52060 is a high efficiency stereo class-D
audio amplifier with adjustable power limit function.
The loudspeaker driver operates from 8V~26V
supply voltage. It can deliver 20W/CH output power
into 8Ω loudspeaker within 1% THD+N at 24V
supply voltage and without external heat sink when
playing music.
AD52060 provides parallel BTL (Mono)
application, and it can deliver 40W into 4Ω
loudspeaker at 24V supply voltage. The adjustable
power limit function allows user to set a voltage rail
lower than half of 5V to limit the amount of current
through the speaker.
Output DC detection prevents speaker damage
from long-time current stress. AD52060 provides
superior EMC performance for filter-free application.
The output short circuit and over temperature
protection include auto-recovery feature.
