Hi Anandkumar,
AD5428 multiplying DAC needs both OUT1 and OUT2 nodes at the same potential to function.
As OUT2 is at ground, OUT1 has to also be at ground potential. Feedback around the op amp forces this to happen.
BTW, AD5428 requires 47ns for the…
For the AD5428, I want to run this DAC from a 3v3 or 5V rail (Vdd), supply the input lines (8 bit parallel input) with 3v3 ttl signals, and have a reference voltage of 5V. Can I supply the 8 input lines with 3v3 ttl signals if I run the DAC from 3v3 or…
