Note 2:
Reduced digital code range (code 24 through code 232) is due to swing limitations of the output amplifiers. See
Typical
Operating Characteristics.
Note 3:
Reference input resistance is code dependent. The lowest input resistance occurs at code 55hex. Refer to the
Reference
Input
section in the
Detailed Description.
Note 4:
Guaranteed by design. Not production tested.
Note 5:
Input capacitance is code dependent. The highest capacitance occurs at code 00hex.
