AD52067-2x16W Stereo/1x20W Mono Class-D Audio Amplifier With Built-in Step-up ConverterDataSheet

Description
The AD52067 is a high efficiency stereo class-D
audio amplifier with built-in boost DC-DC converter.
The loudspeaker driver can deliver stereo 16W/CH
output power into 4Ω loudspeaker under 10%
THD+N at two-cell Li-ion battery (7.4V).
AD52067 provides parallel BTL (Mono)
application also, and it can deliver 20W into 4Ω
loudspeaker at 7.4V supply voltage.
Output DC detection prevents speaker damage
from long-time current stress. AD52067 provides
superior EMC performance for filter-free application.
The output short circuit and over temperature
protection include auto-recovery feature.
