I had to define these pins in aad8402 sketch. Most orders ship within 48 hours of this date. The package for this IC i. On closer inspection i found the AD takes an 11 bit instruction and the AD takes a 10 bit.

Can you post a schematic of what you actually built?

I will try and continue this tomorrow. The AD has eight pots so it needs three bits to address 0 to 7. First off, hit the modify button and highlight the code and click on the icon. The Purchase button will be displayed if model is available for purchase online at Analog Devices or one of our authorized distributors.
