DC and AC electrical specifications do not apply when operating the device beyond its specified operating conditions. Note 3:The maximum junction temperature of the DAC0800 and DAC0802 is 125˚C. For operating at elevated temperatures, devices in the Dual-In-Line J package must be derated based on a thermal resistance of 100˚C/W, junction-to-ambient, 175˚C/W for the molded Dual-In-Line N package and 100˚C/W for the Small Outline M package. Note 4:Human body model, 100 pF discharged through a 1.5 kΩ resistor. Note 5:Pin-out numbers for the DAC080X represent the Dual-In-Line package. The Small Outline package pin-out differs from the Dual-In-Line package.

B1–B8 have identical transfer characteristics. Bits are fully switched with less than 1⁄2 LSB error, at less than±100 mV from actual threshold. These switching points are guaranteed to lie between 0.8 and 2V over the operating temperature range (V LC = 0V).
