Other Parts Discussed in Thread: TINA-TI, TLE2027, TLC27L2
Tool/software: TINA-TI or Spice Models
Hello,
I am using a TLE2027 op-amp in several places in one of our products. I would like to use a spice simulation of one or more of these circuits. The datasheet "SLOS192C− FEBRUARY 1997 − REVISED APRIL 2010" , page 33, contains a listing of a spice model which I copied from the datasheet into my spice circuit. I have also included it below. Unfortunately the TLE2027 model does not run because it is not complete. There are instances of a diode called 'dz' but there is no definition of what dz is. By contrast, there are also diodes called 'dx' and there is a line towards the end of the sub-circuit that defines what dx is.
If I edit the model to change all the instances of dz to dx, I can make the model run, but it doesn't match what was written in the datasheet! Is this hacked model trustworthy?
Is a more recent spice model of the TLE2027 available?
I tried looking at TINA for a spice model but when I opened up the TLE2027 component there I found a sub-circuit (.SUBCKT) for a TLC27L2. That doesn't look right. The TLE2027 has bipolar inputs and the TLC27L2 is CMOS?
Editted to add
Forgot the spice model:
