with Voltage Output
_______________________________________________________________________________________ 5
Note 1: INL guaranteed between codes 40 and 16383.
Note 2: Offset is measured at the code that comes closest to 10mV.
Note 3: Accuracy is better than 1.0 LSB for V
OUT
= 10mV to V
DD
- 180mV. Guaranteed by PSR test on end points.
Note 4: R
L
= open and digital inputs are either V
DD
or DGND.
Note 5: INL guaranteed between codes 80 and 16383.
