Hello Grant Dean,

follow this link http://cache.freescale.com/files/32bit/doc/data_sheet/KL25P80M48SF0.pdf?fpsp=1&WT_TYPE=Data%20Sheets&WT_VENDOR=FREESCALE&WT_FILE_FORMAT=pdf&WT_ASSET=Documentation. Page 9 (Voltage and current operating ratings), it should be applied also for analog pins.

Thank you. I have found that the rated current for analog inputs is different depending on what state the board is operating in. if it is just wait then it is much lower current, and if it is in a running mode the current is much higher.
