onsemi NCP9004
The NCP9004 is a cost−effective mono Class−D audio power amplifier capable of delivering 2.65 W of continuous average power to 4.0 W from a 5.0 V supply in a Bridge Tied Load (BTL) configuration. For cellular handsets or PDAs it offers space and cost savings because no output filter is required when using inductive tranducers. With more than 90% efficiency and very low shutdown current, it increases the lifetime of your battery and drastically lowers the junction temperature.- Min Voltage : 2.2V
- Max Voltage : 5.5V
- Channels : 1
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
