1. Introduce
SL-A01 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 15W at RL=6Ω,VCC=15V,BTL
Rating 10W at RL=4Ω,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 (5mA Typical at 12V) 
• Low Current in Shutdown Mode (<1µA Typical)
• Separate VCC & PVCC
• Class-D audio design
• Components use SMT decal, the board dimension is very small
• IC decal is TSSOP20
• 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 42mm×30mm
