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 50W/CH output power

into 4 loudspeaker within <10% THD+N at 21V

supply voltage.

AD52095 provides parallel BTL (Mono)

application, and it can deliver 100W into 2

loudspeaker within <10% THD+N at 21V 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.
