How to setting ADC in Processor Expert?

Hi,

We are trying to measure current in S12ZVCA project. The current range is -500A ~ +500A. We will use current shunt and OPAmp to convert current to voltage.

Does the S12ZVCA support -2.5V ~ +2.5V ADC reading? Do We need 2 ADC channels for positive and negative voltage reading?

We need to calculate capacity of power. We are setting the 64MHz clock(Bus clock=32MHz).

What is the relation of Number of conversion and Conversion time ?

Do you have any recommend?

Best Regards,

Aaron

Hello Aaron,

- "Conversion time ": The time for one conversion。

-“ Number of conversion ” ：To be more precise , we can use average ADC data, so the Number of conversions

is the numbers of one measurement.

-“Does the S12ZVCA support -2.5V ~ +2.5V ADC reading? ”

I think the S12ZVC ADC only can read positive data ,so you need convert the negative to positive .

While do you mind create a new case about this question to S12Z hardware thread to make sure :

S12 / MagniV Microcontrollers

Have a great day,
TIC
