I'm having problem in converting square to triangle wave through the AD537 VFC.
Referring to the application notes Figure 28:- https://www.analog.com/UploadedFiles/Application_Notes/511072672AN277.pdf
AD537 has the ability to generates triangle wave through the used of AD521 (Precision Instrumentation Amplifier). However, i built an instrumentation amplifier circuit using 3 op-amps (NE5532P)https://www.ampslab.com/PDF/ne5532p.pdf to replace it. The figure is shown in the attach file.
The problem is i can't get the triangle output that i want. Please help me to check what is wrong? Thank You.
