How is the AD5443 quoted at 0.6uA Idd in the spec table but in the TPCs (Typical Performance Characteristics) it reads in mAs?
To clarify the 0.6uA in the spec table. This is the current consumed by the switches when no voltage is applied to the reference and when the digital input voltages are OV or Vdd.
The supply current drawn by the DAC is chiefly determined by the logic levels. The TPC shows the variation in consumption when the digital input voltage levels are swept from 0V to 5V. It is clear to minimise Idd the input logic levels should be as close to 0V and +5V supply rails as is practical.
