Function
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 DV
potential and must not be more than 0.3 V apart even on a transient basis. This supply should be decoupled
to DGND.
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 AV
and DV
output pins can interface to 3 V logic.
