I'm going to use the OP77S, the space qualified version and I also would like to simulate my circuit with spice.
But on the OP77S product page there is no spice model and on the product page of the OP77 (commercial) there are five model proposed…
I am using an OP77F as a differential amplifier to amplify the voltage across a shunt resister. The shunt resister is 0-50mV for how many thousands of amps runing through it. The shunt resister is on the low side, on the common cable of the DC lines.
We just want to design a differential amplifier
As a reference OP77 datasheet page11
Can you provide these simulation example?
Please expound on the discussion of open-loop gain linearity on page 10 of the OP77 Rev E datasheet. The write-up does not go into much detail and the plots confuse me. Both graphs plot some unknown voltage Vy versus the circuit output voltage Vx. What…
thank you for the reaction on my posting.
The background of my question is: I was trying to figure out differences between the OP77(E) and the OP177, but could not make out anything significant in the datasheets, so I wanted to compare the…
The OP07 is over 35 years old. The generations have been OP77, 177, 2177, and now ADA4077 and ADA4177.
For most general work, you could use the OP2177 model.
Op amp models are macromodels, not primitives, so the model writer can add as much or as…
what is Y1 in your schematic. I do not follow exactly what you are doing but you can look at figure 36 of OP77 datasheet hwich gives you detection and amplification. You may need to do adjustment for your needs.
Sure. About 1970, with the 741 op amp, etc. analog signal paths were designed with +/-15V.
PMI introduced the OP07 in 1974. Since that time, we have done several more generations of the
OP07 -> OP77 -> OP177 -> OP1177. The OP2177 is…
