Hi All,
I have seen some active sensors are powered using current and voltage sources.and the output is measured using the ADC"s in the microcontroller, so my doubts is why some peoples are using the current source to drive the sensosr and then convert to voltage source using the current to voltage converter then measures the ADC voltage, instead of driving it with voltage source.

Regards,
Arhu

Why don't you show them to us, too?

Then maybe we could answer your question.
