What is the actual Peak-to-Peak value of the triangle output? According to the application notes., it stated 3.6Vp-p?
I have changed the pullup resistor value on pin 9 to (475) & i replace the resistors of the IA to original values (all 10k except for the gain set resistor 20k).
I connected the unused OP-Amps (inv input to output), and with the noninv input grounded.
Still i can't get the triangle output. I don't know what's wrong. I'm pretty sure my wiring connection is correct! I have troubleshoot it more than one week...
