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=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　 4.
