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 ?
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…
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 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…
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…
Hi again. krisf 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.
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??
