EUA2034
3-W/CH Stereo Filter-less Class-D
Audio Power Amplifier with Auto-Recovery
DESCRIPTION
The EUA2034 is a high efficiency, 3W/channel stereo
class-D audio power amplifier. A low noise, filterless
PWM architecture eliminates the output filter, requiring
only two external components for operation.
Operating from a single 5V supply, EUA2034 is capable of
delivering 3W/ channel of continuous output power to a
4load with 10% THD+N.
The EUA2034 is available in space-saving SOP-16
package.
FEATURES
Unique Modulation Schema Reduces EMI Emissions
3W Output at 10% THD with a 4Load and 5V
Power Supply
Low Quiescent Current and Shutdown Current
Low THD+N and Low Noise
Efficiency up to 87%
Short Circuit Protection with Auto-Recovery
Thermal Protection
Optimized PWM Output Stage Eliminates LC Output
Filter
Available in Space-Saving SOP-16 Package
RoHS Compliant and 100% Lead(Pb)-Free
Halogen-Free
Typical Application Circuit
APPLICATIONS
LCD Monitors / TV Projectors
Notebook Computers
Portable Speakers
Portable DVD Players, Game Machines
Cellular Phones/Speaker Phones
