AD52095-2x40W Stereo / 1x80W Mono Class-D Audio Amplifier With Power Limit  DataSheet
Description
The AD52095 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 40W/CH output power
into 4W or 8W loudspeaker within 1% THD+N at 24V
supply voltage.
AD52095 provides parallel BTL (Mono)
application, and it can deliver 80W into 2W
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. AD52095 output short
circuit and over temperature protection include
auto-recovery feature.
