NOTE FOR ALL CIRCUITS:
THE DEMO BOARD AS SHIPPED SHOWS THE MOST COMMON FUNCTIONS FOR TWO
ELECTRICALLY ISOLATED CIRCUITS. THIS DEMO BOARD WAS DESIGNED TO SHOW CASE THE
MAXIMUM NUMBER OF EVALUATION OPTIONS THAT CORRESPOND TO THE CIRCUITS IN THE
DATA SHEETS BOTH ICs. HOWEVER, THERE ARE SOME IMPORTANT RULES TO ALWAYS
FOLOW:
1. NEVER INSTALL U1 (TOP LAYER) AND U3 (BOTTOM LAYER) AT THE SAME TIME. INSTALL ONE
OR THE OTHER, BUT NOT BOTH.
2. NEVER INSTALL U2 (TOP LAYER) AND U4 (BOTTOM LAYER) AT THE SAME TIME. SAME AS 1.
3. JMP1-4 ARE MEANT FOR SIMPLE DIODE-OR OPERATION. THEY MUST BE REMOVED FOR
PROPER BACK-TO-BACK ISOLATION.
THERE ARE MORE GUIDELINES SPECIFICALLY FOR CERTAIN CIRCUITS. PLEASE SEE THE QUICK
START GUIDE FOR MORE APPLICATIONS AND INFORMATION.
