Content:

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=4Ω,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 (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
