• RE: op-amp input current with voltage on input during powerdown

    Thanks. Yes, I found the ADA4096-2 and the ADA4177-2. The ADA4177-2 has lower input bias current but the packages are larger than the ADA4096-2 in LFCSP.

    The OVP feature prevents damage in my example but I'm not sure whether operating within the OVP window…

  • ADA4177

    We have purchased ADA4177 IC from Element14 , QTY 1000 for company requirement.
    But frequent failure observed for same IC in our PCB where we are using IC ADA4177 (at location U3 only, though U11 is also same IC). We have done failure part analysis at…

  • ADA4177-


    Can I use the opamp ADA4177-2 in single supply operation?

    It is specified for +/- 15V.

    Can I apply 28V dc to positive supply rail V+ and ground V-

    I plan to bias the input to the chip at 14V dc.

  • RE: CN0336 Input protection


    the best way to protect the input from the OVP is to use ADA4177-2 since it has an integrated input protection during overvoltage conditions.



  • ADA4177-4

    This is a simple circuit intended to replace any dual op-amp in dip 8 pkg.

    Short question is , is there any tendency on this part (ADA4177-4) to self oscillate? Probably not but wanted to ask.


    I have a new layout that is self oscillating…

  • RE: 32位ADC芯片的前端设置问题

    1. 这三款ADC的性能都不错,输出速率都能高于1kHz

    2. 推荐您使用LT5400配合ADA4177使用

  • RE: Using The ADA4177-2 as a buffer, outputs don't exactly follow inputs

    I'm surprised it is doing anything. 

    --  You need at least 5V across the part to wake it up

    --  It is not RR input;  you need to stay at least 1.5V away from either rail.

    Try an ADA4084-2 or an ADA4528-2

    For the LMC662,, you could also look at:

    Hello Kris,

    Thank you for your answer.

    We weill confirm ADA4177.



  • What power-supply considerations affect the precision of the ADA4177?

    The ADA4177 is designed to be robust when powered from a variety of power supplies. With an excellent power-supply rejection ration (PSRR) of 145dB, it can tolerate significant supply noise. When calculating the total precision of a signal path, be…
