Datasheet

MAX5222
Dual, 8-Bit, Voltage-Output
Serial DAC in 8-Pin SOT23
_______________________________________________________________________________________ 3
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.
