Part Number:TPL5010
Datasheet的7.5中有关于Digital conversion of external resistance (Rext)的功耗,
请问,这个功耗应该怎么理解,和总体功耗有什么关系?
谢谢!

追加问题:特别想知道,这个功耗是在什么阶段发生的?

非常感谢,我已经知晓了。
R_ext is needed to select the time interval. If R_ext is not present, the nanotimer will not be able to select a T_IP. After the resistance reading, R_ext could be removed. You do not need to remove the resistor in this case to hit 50uA target.
