Hello AD Experts,
I am using AD9042 for Digital Control of Power Supply.
I am using FPGA as a digital controller which operates on 3.3V only. But here it is mentioned that the AD9042 requires 5V analog and digital power supply.
But absolute maximum ratings suggest it can operate in 0 to 7V for both analog and digital power supply.
I am not cleared whether I should proceed further for 3.3V analog and digital supply or not.
Can you also provide application circuits for the same?
Thanks and Regards
The Absolute Maximum Ratings voltages are not operating voltages, but stress ratings beyond which could damage the part.
The AD9042 requires 5V power supplies. Page 15 of the datasheet states that AVcc must be within 5% of 5V. I'm sorry but 3.3V will not work.
