XA9523
2x16W Stereo / 1x20W Mono Class-D Audio Amplifier 2x16W Stereo / 1x20W Mono Class-D Audio Amplifier With Built-in Step-up Converter
产品描述
The XA9523 is a high efficiency stereo class-Daudio 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).
XA9523 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. XA9523 provides superior EMC performance for filter-free application.The output short circuit and over temperature protection include auto-recovery feature.
