MAX522
Dual, 8-Bit, Voltage-Output
Serial DAC in 8-Pin SO Package
_______________________________________________________________________________________ 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. 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.
