Low-Cost, Triple, 8-Bit Voltage-Output DACs
with Serial Interface
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +4.5V to +5.5V for MAX512, VDD = +2.7V to +3.6V for MAX513, VSS = GND = 0V, REFAB = REFC = VDD,
TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

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 VSS to GND.
