MAX5223
Low-Power, Dual, 8-Bit, Voltage Output
Serial DAC in 8-Pin SOT23

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.
