(1)
Typical values are measured with V
REFHI
= 2.5 V and V
REFLO
= 0 V. Minimum and Maximum values are tested or characterized with
V
REFHI
= 2.5 V and V
REFLO
= 0 V.
(2)
The DAC output is monotonic.
(3)
The DAC can generate voltages outside of this range, but the output voltage will not be linear.
