Hi,
About VCIR of LMV393, please let questions.
The LMV393 use with Vcc=+5V.
From the data sheet(SLCS136T), VCIR (Common-mode input voltage range) is specified in the -0.1V to +4.2V.
To us IN- (4pin) terminal, input signal voltage range 0V to +5V.
1)But enter the higher voltage (to +5V) VCIR, Do you have a problem?
2)Between the input signal voltage is +4.2V to + 5V, the output is changed (inversion, etc.) would you like to do?
(Output is hoping that does not change → In the simulation results of TINA, output did not change.)
Best regards
