digital audio amplifier module

Place of Origin:	Guangdong

Location:	Dongguan, Guangdong, China (Mainland)
Business Type:	Manufacturer

Model No.:	SL-A01

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
