Hello:
does s32k1xx series or s32k3xx series has differential pins for ADC? or do we have any way to capture differential inputs?
BR!
Thank you for your interest in our products and for contributing to our community.
The ADC modules of S32K1 and S32K3 devices do not support differential inputs, just single ended. So, it is needed an external circuitry perform differential input.
On the other hand, other automotive products can perform ADC differential input mode operation:
- For S32M2 please refer to Differential Programmable Gain Amplifier (DPGA_AE) chapter of its reference manual.
- For S32K39/37/36 please refer to SIGMA DELTA ANALOG TO DIGITAL CONVERTER (SDADC) chapter of its reference manual.
I hope this information is helpful.
