Note 2:
Digital code from 24 through 232 are due to swing limitations of output amplifiers on DAC A and DAC B. 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.
Note 6:
For single-supply mode, tie V
SS
to GND.
