Datasheet

MAX512/MAX513
Low-Cost, Triple, 8-Bit Voltage-Output DACs
with Serial Interface
_______________________________________________________________________________________ 3
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 V
SS
to GND.
