AD8303–SPECIFICATIONS
Typical readings represent the average value of room temperature operation.
1 LSB = 0.5 mV for 0 V to +2.0475 V output range. The first two codes (000
Includes internal voltage reference error.
These parameters are guaranteed by design and not subject to production testing.
All input control signals are specified with t
The settling time specification does not apply for negative going transitions within the last 6 LSBs of ground.
See Figure 6 for a plot of incremental supply current consumption as a function of the digital input voltage levels.
