LMP7711: Input voltage range

Part Number: LMP7711
Other Parts Discussed in Thread: TINA-TI

Hi Team,

Would you advise that as for the input side terminals (+ IN, - IN),

as an absolute value, what kind of lower limit can be detected up to what V can be detected normally?

It refers to the voltages of + IN and - IN, not the offset voltage.


Best regards,


  • Hi Kiyoshi,

    I'm not sure what you mean. The common mode input voltage range? It's -0.3V...VCC-1V and can be found in datasheet.

    Or do you mean the minimum input voltage the LMP7711 can handle? There's no limit. The LMP7711 works linearily down to infinite small input voltages. The only practical limit is noise.

    Does this answer your question?

  • In addition consider downloading the free SPICE simulator from TI, TINA-TI at:

    By building and simulating your circuit in TINA-TI many problems can be avoided before building it in the real world. If you have problems once the circuit is built in TINA-TI feel free to post the schematic from TINA-TI on the E2E Forum for further assistance.


    We assume this resolved your issue. If you need to ask further questions you can post a new “Reply” or start a new post if it is an unrelated issue.



  • Kai-san Tim-san
    Thank you so much for your advice.
    I found the range of (V+) +0.3V, (V−) −0.3V in datasheet and I will inform this to the customer.
    I have already TINA-TI.
    Thanks anyway
    I'll close this question.
    Best regards,
  • Hi Shidara,

    you are correct, the input voltage range V(-) - 0.3V...V(+) + 0.3V is specified in the absolute maximum ratings of datasheet. This is the range which the inputs can withstand without getting damaged. But to make the OPAmp work properly the input voltages must not violate the common mode input voltage range which is V(-) - 0.3V...V(+) -1V. See also the specifications of "common mode voltage range" on page 3 and 4 of datasheet.
