LMV341-Q1: the specification of VICM

Part Number: LMV341-Q1
Other Parts Discussed in Thread: LMV341

Dear all,

Could you teach me about the specification of VICM at V+=5V?

You define that Typ: -0.2~4.2V and Max: 4V.

Why maximum value is lower than typical value?

In addition, this specification is defined with Ta=25C, so the 4V is also typical value.

How should I think about these tipical value?

And, what is the maximum value over full range?

Best regards,

    Takao-san,

    The maximum/minimum specifications are the tested limits.

    You should think about the typical value as representing the parametric norm of the devices when the device was characterized.

    Another way to think about it is shown in the LMV341 (non-Q) data sheet. Please take a look at it because it may make it more clear.

    I am not sure what you mean by "...maximum value over full range." Please clarify.

    Tako-san,

    I will tackle the specmanship question .

    You define that Typ: -0.2~4.2V and Max: 4V. Why maximum value is lower than typical value?

    Note the typical value is a "range". Therefore the data sheet (min/max) limits must be inside the range.    

    See green squares. If application stays within 0V to 3.9V common mode (for VCC =5V) then expect 47db rejection or better. That means this common mode range works across temperature.
