• OP2177

    Hello=),

    I just encountered a unit, having a solder bridge between pin7(outB) and Pin8(V+).

    After having it analyze at FA, it was found to have a burnt metallization directly connected to pin1(outA).

    Is the event of burnt metal on Pin1(outA) a possible…

  • op2177: Single supply operation

    Q 

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

     

    A 

    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…

  • OP2177 protection diode

    Hello

    We will use OP2177.

    In absolute maximum rate of the datasheet, input range is -Vs ~+Vs.

    The datasheet of opamp usually include  the description of  power supply +- 0.3V at input

    Does OP2177 include  a protection diode at input stage ?

    If not so…

  • frequency response of OP2177

    Dear Sir/Madam,


    We are using OP2177 OP-amp for voltage follower (Av=1).

    Pls refer to Figure33 of page10.

    Q1.We think the frequency response of voltage follower is ( Av = 1 plot ) of Figure33.
         Can we think that the frequency response of the inverting…

  • 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;

    Bell

  • Power supply sequence of OP2177

    Dear Sir/Madam,

    We think that we will use OP2177 OP-amp.

    Please teach us the power supply sequence (+V,-V) when power-on/off.

    Our system can't supply +V/-V simultaneously.

    It would be greatly appreciated if advice could be gotten.

    Best Regards…

  • OP2177 will be replaced with OPA2180

    Hello

    I want you to give us advice.

    OP2177 is targetted to be replaced with competitors, OPA2180 and so on.

    We try to promote ADA4077-2A. But they mentioned TCVos is worse than OP2177. They don't want to use it.

    ADA4522-2 doen't seem to compete…

  • OP1177 / OP2177 / OP4177 Input impedance

    Q 

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

     

    A 

    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…

  • OP2177 单电源供电

    OP2177这款运放能否采用单电源供电，例如VCC+接入+15V，VCC-接GND，有什么影响？

  • OP2177驱动电流问题

    想问一下OP2177的最大输出电流是多少？输出电流跟输出电压之间的关系有没有图能反映出来？

    另外如果把OP2177做成电压跟随器的话，输出电流又是怎么样个情况呢？请指教，谢谢
