AD52067-26QG28NRR
The AD52067 is a high efficiency stereo class-D audio amplifier with built-in boost DC-DC converter. The loudspeaker driver can deliver stereo 15W/CH output power into 4Ω loudspeaker under 10% THD+N at two-cell Li-ion battery (8.4V).
AD52067 provides parallel BTL (Mono) application also, and it can deliver 19W into 4Ω loudspeaker at 8.4V 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.
