Dear supporter

The AD9508 CMOS Voutput level in DS page 6 = 1.7V min:

Test Conditions/Comments

Output Voltage

At 1 mA Load

Pls advise what to do in case of using the DDS AD9914/5 which needs at its CMOS input a min voltage level of 2.0V,as found below:

CMOS LOGIC INPUTS (table 1- page 4)

Input High Voltage (VIH) 2.0  (MIN)   

 

Thanks
