EUA2034 Datasheet | Eutech Microelectronics

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 ponents for operation. Operating from a single 5V supply, EUA2034 is capable of delivering 3W/ channel of continuous output power to a 4Ω load 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 4Ω Load 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 Ro HS pliant and 100% Lead(Pb)-Free Halogen-Free APPLICATIONS LCD Monitors / TV Projectors Notebook puters Portable Speakers Portable DVD Players, Game Machines Cellular Phones/Speaker Phones Typical Application Circuit Vm Ry w‘ fo b w .go w w om c . h tec Figure1.
