Accuracy and supply — the specs that decide fit
INL of +0.16/-0.12 LSB and DNL of +0.04/-0.02 LSB are tight for an 8-bit DAC. The single supply rail from 2.7 V to 5.5 V matches the common MCU supply range. The reference type is supply-referenced, meaning the output full-scale equals the supply voltage.
Temperature grade and environment
Rated for -40°C to 105°C, this part suits industrial environments — motor drives, outdoor telecom cabinets, factory-floor sensors, and engine-bay electronics that stay below the 105°C ceiling. It is not AEC-Q100 qualified, so for automotive under-hood or chassis-domain applications, look for a qualified sibling in the DACx8S101 family. The 8-VSSOP package (3.00 mm width) fits tight PCB layouts; the surface-mount footprint is standard for low-pin-count analog ICs.
