• AD8671

    Hello

    What is the maximum input current of the AD8671?

    Because the power supply sequence of the AD8671 is as follow.

    1)-5V is applied to the V- terminal

    2)4V is applied to the +IN terminal

    3)15V is applied to the V+ terminal

    Since I think that the current…

  • Question for AD8671

    Dear Sir/Madam,

    I have a question for you.

    If the load(RL) is open(infinity) on Vs=+/-5V supply, what are the min VOH and VOL?

    Your datasheet show 3.8V and -3.8V when RL=2kohm.

    AD8671 isnt rail to rail device.

    I think that they are similar 3.8V/…

  • RE: Heat problem in AD811ANZ

    Just change to an ADA4084-1, ADA4610-1, or AD8671 and the power dissipation will

    be a lot less.

  • RE: ADA4807-2 become very heat when it put-in a ±5v circuit?where is  the reason?

    Thank You for your reply.

    I don't give input signal, I just solder ADA4807 on the PCB, and I have try another ADA4807, but all of them generate heat . 

    when I use AD8671 or ADA4841, they are normal. they have same the define of Pin.

    Dear Grzegorz,

    Thanks for providing the previous helpful answer.

    We are trying to perform an exhaustive failure analysis (in the limits of practicality).

    I am including a pseudo-netlist of the PLL loop filter.

    Could you respond if with such filter…

  • RE: Droop/backswing in 3-stage amplifier

    Walter,

      As Jon pointed out, the Vos of the first stage gets multiplied by the overall gain.

    Second, The AD797 has extremely high gbw and is very hard to use.  People call in all the

    time with oscillations;  I'm amazed your board works at all.  It…

  • RE: can OP07 be used with single supply ??

    Yes, but not with 5V;  you need at least 6V across the part.

    But why choose  an OP07 that is over 30 years old?  We have done many generations in the OP07 family,

    OP07 -> OP77 -> OP177 -> OP777 -> OP1177 -> AD8671/8675 -> ADA4077-1.

  • RE: OP177G / Difference Amp

    Husein,

      We have done quite a few generations of the OP07 family:

    OP07(1974) -> OP77(1988) -> OP177(1989) -> OP777( OP1177(2001) -> AD8671/8675/8677(2003) -> ADA4077(2014) -> ADA4177(2015)

    With the high gain, I would not use any of…

  • RE: Will there be a dual version ADA4627-1.

    Bryan,

    I wish you would have gotten a name so I could track this down further.  Was it a local field office

    or an office in Norwood?   Which department?  That is certainly unacceptable behavior.

    I was the product line apps engineer for the ADA4627-1.
