Hello All,

 

We are trying to implement frequency change of sine wave in AD1836 at BF-533 EZ-Kit.

We have generated the LUT for sine wave and changing the freq. and doing interpolation.

 

we are getting sine wave but frequency is not correct.

Frequency is 16 times more than actual value.

 

What should be the reason for it?
