S32K312 ADC INPUT Circuits

[KarthikRaja]

Hi 

From current sense amplifier and voltage driver I am getting voltage and current data which I wanted to to assign in ADC Pins of S32K312 MCU. Right now I am directly giving the voltage and current data to MCU ADC pins. Does any circuit require for better calibration?

Regards

Hi @KarthikRaja,

If you need calibration or increased accuracy, you can look at the following documents for the ADC:

• AN12217: S32K1xx ADC guidelines, specs, and configuration (chapter 3. Best practices to increase accuracy)
• AN5032: Reference Circuit Design for a SAR ADC in SoC

Best regards,
Julián
