Hi,
I’m Giacomo, electronic engineer from Loccioni Group.
We are testing the ADC 7902 in the range 0-5V, and we have an issue in ADC conversion.
The conversion curve (Volt to counts) is linear in most of the range but there is a windows of about 600 counts, starting at exactly 50246 counts, where the characteristic is constant.
We found this problem in a dozen devices, in different configurations.
Can someone help me?
Best regards,
