Note 1:
The outputs may be shorted to V
DD
or GND if the package power dissipation is not exceeded. Typical short-circuit current to
GND is 70mA.
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. See the
Reference Input
section.
Note 4:
Guaranteed by design. Not production tested.
