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 8? loudspeaker within 1% 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 4?

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.
