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
