ADC I/O Pin Ratings for the FRDM KL25Z
Hi, I was wondering if someone could clarify the voltage and current operating conditions of the analog to digital input pins on the FRDM KL25Z? I have a FRDM-KL25Z128VLK4 microcontroller and have read the documentation, but am still having trouble. I believe the operating voltage for the pins is 1.7-3.6V or 3.3V. I am unsure on the current.
I am using a voltage divider and a current sensor so that the microcontroller's analog inputs can read my systems output. I just want to be sure I have lowered the voltage enough and regulated the current properly for the analog in pins. I would greatly appreciate the help!
