• OP177 SPICE model

    I have downloaded the SPICE model file for the OP177 but found that it actually contains the model for the OP1177.

    Where can I get the proper SPICE model file for the OP177 ?

  • Offset Voltage adjustment for OP177

    Dear Sir/Madam,

    Our customer asked th following question to me.

    As for your OPAMP OP177GSZ,

    your datasheet shows the adjustable offset voltage adjustment range is +/-3mV typ by adding 20kohm POT on Rp.

    So if we need it +/-6mV, then what is the external…

  • AD711 replacement solution

    Hello there

                       Ask everyone, what alternative chip or solution is there for the AD711 chip,

    can OP07 or OP177 completely replace the AD711? Or there are other better chips.

       

                                                                                                                       Thanks everyone…

  • RE: OP177G / Difference Amp

    Dear Harry,

    Thanks for the informative reply. I have hit the books since your reply and made an excel sheet that incorporates all the details (input offset volts, current, input bias current, Rth of the wheatstone bridge). Waiting to get back to office…

  • AD620, digitally adjusted reference pin

    Hi,

    I use AD620 in order to amplify my loadcell signal. I have +/-15V present. I regulate these voltages to 10V and -11V. I use 10V to excite loadcell. Also I use 10V to power AD620 and OP177 op-amps. (There is a filtering circuit after AD620 with couple…

  • 442 - I cannot find the datasheet for the 442 (old OPAMP Module)

    I cannot find the datasheet for the 442 (old OPAMP Module)

     

    Please find attached.

    A suitable replacement is the OP177 or OP1177.

    你好,

            咨询一下大家,AD711芯片有什么替代芯片或方案,OP07货OP177可不可以完全替代AD711? 

     

            感谢各位!

  • RE: OP-177

    Hi again. can ı ask you another question. When ı read op177 datasheet and ı see typical offset voltage is 40 uV but ı set up test circuit my offset voltage 5 mV. Maybe this is a problem. What can ı do for this.

    dclm,

      20V / 65536 =  305 MICROVolts??  Not millivolts??  Do you mean microvolts all the way though your reply?

    Is this measured at the output of the AD620 or the second OP177??

    Is your "16bit A/D module" a monolithic IC or truly a module??
