Product Details

 


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
