Low-Cost, Triple, 8-Bit Voltage-Output DACs

with Serial Interface

_______________________________________________________________________________________

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.
