Hi,

 

I have a problem about replacing AD5933 to AD5934 in my electronic board . I use AD5933 in my board with external oscilator without any problem for more than 2 years. Due to reduce to cost when I tried to replace AD5933 to AD5934 I couldnt  get any accurate impedance. I can communicate with AD5934 but I receive wrong data.  I changed only AD5933 on my board. . I also changed Frequency Increment and Start Frequency values as datasheet differences. Simply I did Start and Increment Frequency values multiply by 4. I set for external clock by send 0x04 to 0x81 address. I dont change number of increments and number of setling cycle.

What could be the problem?
