Hi all,
If built a few devices based around the 16f1779, using the onboard op amps. I realise its not the best spec op amp and while they all work, I've noticed a variation in performance.
Its a RFID reading device and I'm happy with how well it works but might make more that need better range.
I've used the cheapest surface mount resistors and capacitors, would folks think spending a bit more on discrete components with better tolerance is the way forward or should I be looking at better spec op amps?
Cheers Geoff
