Product Description

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=6o,vcc=15v,btl rating 10w at rl=4o,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 4. parameter parameter test condition min typ max unit po(max) continuous output power (r.m.s)at 1khz rl=4o 15v not allow w 12v 10.5 9v 6.2 rl=6o 15v max 15 w 12v 9.6 9v 5.4 rl=8o 15v 13 w 12v 8.2 9v 4.5 rl=16o 15v 7.8 w 12v 5 9v 2.71 thd+n vcc=9v, po=3w, rl=6o,f=1kh 0.33 % vcc=12v, po=7w, rl=6o,f=1kh 0.4 vcc=15v, po=12w, rl=6o,f=1kh 0.47 vcc=9v, po=2w, rl=8o,f=1kh 0.26 vcc=12v, po=6w, rl=8o,f=1kh 0.3 vcc=15v, po=9.5w, rl=8o,f=1kh 0.42 output noise vcc=12v, po at thd+n<0.5%, f=1khz gain=20db -70 db s/n maximum output at thd+n<0.5%, f=1khz 85 db crosstalk between outputs vcc=12v, po=1w rl=8o -60 db working voltage 5 12 15 v
