I'm quite confused why the ADCMP60* datasheets (e.g. [1]) claim there is an internal 70 k? resistance when that seems to be inconsistent with everything else in the datasheet.
The only reasonable interpretation of the 70 k? figure, that I can think of, is that the equivalent model* is a 1.25 V voltage source in series with 70 k? (i.e. basic Thevenin equivalent).
The hold mode activates around 1.1 V at the LE/HYS pin, so we don't want more than 0.15 V drop across the resistor. 70k? would limit the current out of the pin to 2?A which is an order of magnitude below the 25?A cited in the datasheet for maximum current out of the pin. There is tons more examples like this in the datasheet that make no sense given this equivalent model and the 70 k? figure.
Is this just a typo or am I mistaken about this model?
It bugs me that all the numbers come out right with 7 k?...
I've tried to ask this question on the analog devices support forum but no luck. Same with their "report error in datasheet" form.
