I would like to interface AD7899 with a FPGA whose I/O levels are 3.3V. In the datasheet specifically it is mentioned that Vdrive can be 5V or 3V. Can i give Vdrive with 3.3V for interfacing FPGA and ADC to fetch ADC data?
Yes the Vdrive can have a 3.3V input to interface with processors and DSPs. As mentioned in the datasheet on the pin description section. The Vdrive can be connected to Vdd or powered by a 3V+/-10%. Please take note that Vdrive should be decoupled with 0.1uF capacitor to DGND.
