  1. How can I connect common cathode LEDs instead of common anode LEDs to ICL7107? (cause I have some LEDs common cathode). Any schematics?
  2. Yevgeni, If a capacitor is marked like this 123, it just means 12+3zeros = 12 + 000 = 12000pF = 12 nF. And that's exactly the way you write it too. Value is in pF (PicoFarads). The letters added to the value is the tolerance. D -> 0.5pF F -> 1% G -> 2% H -> 3% J -> 5% K -> 10% M -> 20% P -> +100, -0% Z -> +80, -20% babisko
