DVDD
Digital Supply Voltage, 2.7 V to 5.25 V. This is the supply voltage for all digital circuitry on the AD7492 apart
from the output drivers and input circuitry. The DVDD and AVDD voltages should ideally be at the same
potential and must not be more than 0.3 V apart even on a transient basis. This supply should be decoupled
to DGND.

VDRIVE
Supply Voltage for the Output Drivers and Digital Input Circuitry, 2.7 V to 5.25 V. This voltage determines the
output high voltage for the data output pins and the trigger levels for the digital inputs. It allows the AVDD
and DVDD to operate at 5 V (and maximize the dynamic performance of the ADC) while the digital input and
output pins can interface to 3 V logic.
