Okay...So trying to work with a comparator referenced to ground.
No.have people found this to be difficult in general?
Well, for the LM393 for example, it's right there on the first page, under Features: "Input Common-mode Voltage Range Includes Ground."So can you help teach me a what to look for in the data sheet that tells me I can ref it to ground
I’m still a bit hazy on all
The CM stuff
What should I be looking for as a spec that allows a ref of gnd?
Yea I saw thatWell, for the LM393 for example, it's right there on the first page, under Features: "Input Common-mode Voltage Range Includes Ground."
Of course it is, provided your circuit does not try to force the non-grounded input more negative than -0.3 volts.That is what I suspected
Is it even possible to have a ref of ground on a single supply comparator?
