Hi, I am trying to find an ADC with the following specifications.
1. Power supply to it has to be less than 3V.
2. sampling frequency is 500ksps.
3. 16 bit.
4. My input signal is varying from 0 to 2V.
When I am trying to find an ADC I came across the following datasheet:
1.Datasheet-1
In it the analog power supply is mentioned as 2.7V to 5.5V, My doubt is can I supply VA with 2.7V? Vdd with 1.8V, Vref with 1.8V ?
2. what is the significance of Vref? what does it do?
3. It also has a built-in conversion clock, what does it do? My understanding is from the host/controller this IC gets the clock to interpret the signals during SPI communication.
