I have some questions about the xr2206 chip and it's use. Data sheet here; http://www.jaycar.com.au/images_uploaded/XR2206V1.PDF
1. The first page says that it can adjust the out put duty cycle from "1% to 99%". But the closest thing to duty cycle on the pin outs is called "syma1(pin15) and syma2(pin16)", is symmetry the same as duty cycle?
2. All I want from this IC is the square wave, do I need to ground the sine and triangle wave out puts or leave them floating?
3. I want to make the frequency adjustable with a pot from 5Khz to 50Khz. Do I hook the pot between the R1(pin7) and R2(pin8) or how is this done?
I'm sure I'll have other questions, but this is a start. Thank you, cary
