I'm having a bit of a problem making a XR-2206 work: it won't work above 12V (or +6 / -6V split), when it should do it up to 26V (or +13V / -13V).
I've been trying the test circuits from the datasheet, and they all seem to work fine, but only as long as I don't exceed +6 and -6 volts (or 12V in the single supply examples).
This is a picture of what I get in an oscilloscope when I pass that voltage:
I also noticed that if I increase the frequency with a pot through the Timing Resistor, it will work with higher voltages -up to the 23 V limit at the maximum frequency- but again, the results get all messed up as soon as I lower the frequency back; so it seems that it needs Vcc to increase along the output frequency.
Is anyone familiar with this IC, or has any idea why I'm getting these results?
Thanks in advance...
