S12ZVC ADC Problem

[maximillion]

Hi,

I am using S12ZVC for my project. I use one ADC component and 5 channel.

I have a current sensor which give output between 2.5-5 Volt. When current sensor output is 2.5 V ADC value is 139. Thats mean current is equal to zero. I am mapping according to this value.
When current sensor output increased ADC value increased. But ADC is very slowly. For example 2.5V is equal to 139(bit value), current sensor output is increasing ADC value increasing but very very slowly and current sensor output is decreasing ADC value very very slowy decreasing. I dont understand why.

Hi @maximillion,

I understand you use the 8bit mode.

Can you post other results at different input voltages?

Can you please use a longer sample time and compare/post the results?

What sensor do you use? Can you share the schematic?

Thank you,

BR, Daniel
