Hi Freaks,
This is part of a more general question I have asked in the off topic forum but I would like to get your opinions on an ESD diode voltage measurement. This is the diode internal to the IC. I am planning to use the AVR ADC to measure this 0.6-0.7V drop. I have already got the attached circuit working with a discrete diode (component)with a lower resistance(about 10K) value. The ESD diode needs about 10 uA current. Will the attached schematic be ok to perform this measurement using the AVR ADC? R = 10k.
Thanks.
