NOTES
1Typical readings represent the average value of room temperature operation.
21 LSB = 0.5 mV for 0 V to +2.0475 V output range. The first two codes (000
H, 001H) are excluded from the linearity error measurement.
3Includes internal voltage reference error.
4These parameters are guaranteed by design and not subject to production testing.
5All input control signals are specified with t
R = tF = 2 ns (10% to 90% of +5 V) and timed from a voltage level of 1.6 V.
6The settling time specification does not apply for negative going transitions within the last 6 LSBs of ground.
7See 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.
