Both the analog and digital supply pins accept 2.7 V to 5 V, so you can power the whole DAC from a single 3.3 V or 5 V rail without a separate analog regulator. That simplifies the power tree on a mixed-signal board, but watch the reference: the part accepts either an external or internal reference, and the output swing depends on the reference voltage you feed it. If you need a rail-to-rail output, this part won't give it — the voltage output is buffered but not rail-to-rail, so check the output compliance against your ADC input range.
Linearity and monotonicity — INL ±0.4 LSB, DNL ±0.1 LSB
The INL of ±0.4 LSB and DNL of ±0.1 LSB mean the part is guaranteed monotonic — every digital code step produces a positive voltage increment. For a trim DAC, that matters: you don't want a code that jumps backward. The DNL figure is tight enough that you won't see missing codes in the transfer curve. If you're using this to set a comparator threshold or a regulator feedback voltage, that linearity buys you repeatable setpoints across temperature.
That rules out automotive under-hood, outdoor telecom cabinets, or any environment that sees freezing or sustained heat above 70°C.
No stock figures here, but the supply channel is open.
