Description
The AD52068 is a high efficiency stereo class-D
audio amplifier with adjustable power limit function.
The loudspeaker driver operates from 4.5V~26V
supply voltage and analog circuit operates at 5V
supply voltage. It can deliver 20W/CH output power
into 8W loudspeaker within 10% THD+N at 24V
supply voltage and without external heat sink when
playing music.
AD52068 provides parallel BTL (Mono)
application, and it can deliver 40W into 4W
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. AD52068 provides
superior EMC performance for filter-free application.
The output short circuit and over temperature
protection include auto-recovery feature.
