• Absolute Maximum Voltage in OP4177

    Hello everybody,

    First of all, thank you for your replies, as this is my first post in this Comunity.

    I have an Analog Input to measure the output signal (in current) of a HV transducer. The transducer is suplied to +- 24V

    The Analog Input consists…

  • OP4177 Power Voltage Supply

    Datasheet is not complete clear to me.

    Does this opamp only work with a negative voltage at v- or can it also work with 0 VDC at v- and 5 VDC at v+?

  • OP4177 Current Limit on Inputs

    If an input exceeds the power supply rails on the OP4177, are there clamping diodes that will protect the device? If so, how much current is allowable?

  • OP4177 unused Op amp section

    Hello

                Customer use OP4177 and just only use three channel. If fourth Op amp not used on their application, Can the op Amp be floating or connect to voltage follower is better? Thank you.

  • OP1177 / OP2177 / OP4177 Input impedance

    I don't find any information about the input impedance in the datasheet. Could
    you provide me any?

     

    We do not have the data that you are looking for. Based on what we know about
    the design, differential resistance is roughly 6 MΩ…
  • OP4177 opamp is not working as voltage limiter.

    Hi!

    I am facing some issues with OP4177 (precision amplifier)  in a voltage limiting application. Earlier in the design LM-148 ( quad uA741) was used and there was absolutely no issue. In the same configuration OP4177 gives horrible results with absolutely…

  • OP4177  as voltage follower for battery cells

    I am using an OP4177 in an externally powered application (voltage follower for battery cells). Is it OK to leave the voltage input from the cells connected when the supply power is off?

  • OP4177: Can I operate this device with a single supply?

    Can I operate OP4177 with a single supply, datasheet only specifies dual
    supplies?

     

    Yes, you can use OP4177 with a single supply but you need to be careful that
    the input or output does not exceed the headroom limitations (1V from both…
  • 问题: 咨询,求帮忙 OP4177

    请问哪位大哥知道op4177一些数据,比如输入电阻、输出电阻、差模增益、失调电压、电流和电压的温漂等。
    数据手册上好像没有这些数据,帮帮小弟,谢了。

  • OP1177/OP2177/OP4177 addtional information on slew rate 

    I'm looking for information about slew rate of the OP2177.

    In the datasheet there is only a typical value with one load  (0.7V/µs).

    Do you have more data:
    - Min / max value over the temperature  range
    - variation with the load
