I am using the device DAC5686. In the datasheet of the product, in electrical characteristics (digital specifications) section, on page 10, it is said that high level input voltage is 2V for IOVDD=3.3V. However, I use IOVDD with 1.8V. So, 2V is not possible for my desgin. What is the minimum high level input voltage for IOVDD=1.8V?
Thanks
