Hello Lars,
i say also thank you for this excellent explanation.
Using a 220k resistor in series with the thermistor should perfectly work for my AD587.
I'm also working on an layout for a small PCB, fitting into a TEKO tin-box (45*48mm).
I will use a small capacitor on the output and connect the output wires directly to small solder pads,
putting some ferrite beads over them, to reduce EMI problems and avoid additional solder joints.
There are also additional pads for 3 types of precision trimmers and for paralleling the trim resistors R01 and R03.
What do you think about a complete ground plane for increasing the "heat" dissipation?
Joe's boards don't use a complete plane. Instead he uses 2 Oz. traces " to minimize errors caused by trace voltage drops".
The whole circuit runs at 2 mA, so i think doing this would be very volt-nutty?!
Best regards
Frank
