I've tried to the spice .subckt models available from AD for the above devices but keep getting an eror message Pin(port) count mismatch between instance and subcircuit in LTspice. I have checked things over and over the only thing that looks odd is the pin numbering .subckt AD8610 1 2 99 50 30 - i.e. it is not sequential in the subcircuit definition - also on the 8331 model characters are used insead of numbers which I doubt LTspice will like!
.subckt VGA VIP VIN MODE ... etc
According to the symbol definition it expects pot numbers ..
Any suggestions please?
