Guys,
I have searched the reference manual but cannot find the input impedance of the ADC pins. Where in this document is the pad information available?
Thanks,
Nick
Hi,
Refer to the AN3971 "MPC567xF/MPC5676R Hardware Requirements/Example Circuits". See both the eQADC overview section and Appendix B "MPC567xF/MPC5676R ADC Input Model".
