Dear sir or madam
We are using LM2903VQPWRQ1, and in datasheet of LM2903-Q1, Common-mode input-voltage range stays below Vcc-2V.
With a note : "The upper end of the common mode voltage range is VCC+ − 1.5 V for the inverting input (−), and the non-inverting input (+) can exceed the VCC level; the comparator provides a proper output state."
Does it mean the inverting input (−) must be lower than Vcc-2V for a proper output?
In our design, Vcc is 5V, V+ is2.8V, V- is 3.9V. Is it OK for a proper output?
Thanks in advance.
Regards,
Ruipeng
