LMV7275: What is the maximum output voltage? Datasheet says conflicting statements.

Part Number: LMV7275
Other Parts Discussed in Thread: TLV1701, TLV7021, TLV1805, TL331

We were just about to release a new design when I ran into a problem with one of your parts, LMV7275MG/NOPB.

 

When I selected the part I was reading the fourth paragraph of section 3 of the datasheet (first page,) which lists the advantage “of allowing the output to be pulled to any voltage up to 5.5V, regardless of the supply voltage of the LMV7275.” This behavior is absolutely crucial in my design.

 

Yet when I look at the absolute maximum ratings, section 6.1 (page 4,) it says that the maximum voltage at Input/Output pins is “(V+)+0.1V

Which statement is accurate?

Thanks,

Lauren

    Hello Lauren,

    The output does have an ESD diode to V+, so the output cannot be pulled above the applied supply voltage.

    The pull-up voltage can be any voltage up to the applied V+ voltage (which is a maximum of 5.5V).

    So while true, the statement is a bit misleading. I'll put that on the to-fix list for the datasheet.

    If you need a device where the output can be pulled above the supply, please see the the following:

    TLV1701 (same pinout  and in SC-70 - can drop-in replace)

    TLV7021 family (different pinout - recommend if you can redesign)

    TLV1805 (different pinout),

    TL331 (different pinout)
