• OP2177


    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…

  • RE: AD5445 single supply application

    I have OP2177 in circuit right now,

    I wrote 0x0XCCC into DAC

    I have 832mV on pin#2 of OP2177 or pin#1 (IOUT1) of DAC

    I have 1249mV on pin#3 of OP2177 or pin#2 (IOUT2) of DAC

    I have -0.005mV on pin #1 of OP2177

  • RE: AD7988-1, differential input, common mode rejection on VCOM

    Hi Richard,

    Are you referring to the IN+ and IN- of the OP2177 or the AD7988? It is not indicated in the datasheet of the OP2177, but the input impedance of amplifiers are generally very high, typically in the range of Mohms or higher. The OP2177 also…

  • RE: anveshan 2015080: AD8606 is getting heated up

    Hi Koushik,

    Glad to hear that it is now working!   What makes you decide to use the OP2177? I've looked the OP2177 product page and I noticed that the ADA4077-2 is recommended as a new alternative parts for this. I am just curious on how you pick…

  • RE: I am trying to model the op 2177 and 1177 in ltspice.

    Hi Matt,

    There is actually an existing model for OP2177/OP1177. Please see this link OP2177. You can use that model in the simulator of your choice, just open the .txt file and create symbol.

    I hope this helps.



  • OP2177 protection diode


    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…

  • OP2177 will be replaced with OPA2180


    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…

  • 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…
