NOTES
1
Typical readings represent the average value of room temperature operation.
2
1 LSB = 0.5 mV for 0 V to +2.0475 V output range. The first two codes (000
H
, 001
H
) are excluded from the linearity error measurement.
3
Includes internal voltage reference error.
4
These parameters are guaranteed by design and not subject to production testing.
5
All input control signals are specified with t
R
= t
F
= 2 ns (10% to 90% of +3 V) and timed from a voltage level of 1.6 V.
6
The settling time specification does not apply for negative going transitions within the last 6 LSBs of ground.
7
See Figure 6 for a plot of incremental supply current consumption as a function of the digital input voltage levels.
Specifications subject to change without notice.
