Product Description

1. Introduce SL-A03 is the new design, it is new product of digital amplifier board,use SMT decal of main IC,connection is very simple. High Power efficiency,Less heat. 2. Aplication Power speaker Digital product Computer and laptop Portable product Wireless product TV, DVD and the other product 3. Feature Output Power: Maximum 16W at RL=4O,VCC=15V,BTL Rating 10W at RL=4O,VCC=12V,BTL Power efficiency is up to 82% Low Working Voltage Down To 5V, High Working Voltage up To 15V Thermal Protection function Output Pin Short-Circuit Protection Low Supply Current (10mA Typical at 12V) Low Current in Shutdown Mode (<1µA Typical) Separate VCC & PVCC Class-D stereo audio design Components use SMT decal, the board dimension is very small IC decal is TQFP48 No external heat-sink, Less heat, save heat sink cost The current is very small The PCB design provides both bead and LC solutions The dimension is only 47mm×40mm 4.
