• op2177: Single supply operation

    We would like to know if the OP2177 amplifier can be used in single-supply


    Yes, you can apply a supplies that are not symmetrical to an opamp. Generally
    speaking, op amps can be used from any supply voltages (symmetrical or

  • 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, common mode…

  • OP2177 - Date Code


    We met some issue on our product with OP2177 device.

    With a date code OP2177 A#830 5002 ==> our product works without problems.

    With a date code OP2177 A#932 6453 ==> our product doesn't work.

    Could you communicate if the PCN#18_0060 is applied…

  • 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


    The slew…

  • OP2177 Silicon Change? Different behavior on newly purchased devices.

    Hi.  In our application, the OP2177 output is disconnected for a period of time, and the feedback loop is broken resulting in the OP2177 output going to one rail or another (+ or - 15 V).  We then close the output relay and the feedback loop is closed again…

  • RE: OP2177 protection diode

    Hi Areski,

    My initial assumption was that this amplifier belongs to the OP07 family. And we should expect similar input protection circuitry. But you can't say anything unambiguous, because there is no uniformity in the data sheets. I believe that OPX177…

  • OP2177: rail-rail input/output

    Hi Team;


    OP2177 at +/ -15v power supply, the input voltage range is +/ -13.5v.

    Is there any device with similar parameter, but is rail-rail input/output at +/ -15V?

    many thanks;
