Hello!
I don't know exactly where I should put this question. I thought that there might be more analog guys here. I'm mostly
dealing with microcontroller, and my knowledge about op amps is quite fuzzy. Please move this message to the proper
section if there is a more relevant one.
I'm using an LMV 358 as a comparator (supply voltage is 3.3V). It works fine and dose exactly what I want.
But one guy who seems to be good at analog hardwae told me that op amps should never be used
as comparators, and that a significant difference between e- and e+ rather than the e+ = e- of linear designs
will cause the chip to grow old early and die.
Could anybody tell me more about this? Will the chip really die if used as a comparator? It's been running
for more than 2 years, but I would really like to know if I should change the design for future products.
Thanks,
Pascal
