I'm looking for clarification as to the input common mode range requirements for the TLC372
My circuit drives a TLC372 comparator circuit through a voltage divider to output a change of state when a threshold level is reached. One input to the comparator is from a precision 2.5V reference.
Datasheet states Vdd – 1.5V – some comparators state both inputs must comply, others that only one input must comply, but this is not clear on the TLC372.
If I’m using a 3V3 single sided supply then the ICM range is only 1.8V, and as I’ve got a 2.5V reference at one input and resistor divided input that may be as high as 7V at the other, I'm concerned the common mode requirement could be violated. Can I have some feedback regarding this matter?
