Hello,
I am looking at the DDC264 current to digital converter chip and want to make sure I am understanding the input limits correctly. Operating in Range 3, the input range has a typical value of 150pC. If I am running at 500uS integration time, then is the current limit 150e-12 / 500e-6 = 300e-6 Amps? What would happen if I feed the input with a larger current, say 1mA? Do you have any current input chips that accept up to 1mA?
Thank you,
Tom
