Note 3: Electrical specifications are production tested at T
A
= +25°C. Specifications over the entire operating temperature range
are guaranteed by design and characterization. Typical specifications are at T
A
= +25°C.
Note 4: DC Performance is tested without load.
Note 5: Linearity is tested with unloaded outputs to within 20mV of GND and V
DD
.
Note 6: Offset and gain errors are calculated from measurements made with V
REF
= V
DD
at code 30 and 4065 for MAX5815,
code 8 and 1016 for MAX5814, and code 2 and 254 for MAX5813.
Note 7: Subject to zero and full-scale error limits and V
REF
settings.
Note 8: Measured with all other DAC outputs at midscale with one channel transitioning 0 to full scale.
Note 9: On power-up, the device initiates an internal 200µs (typ) calibration sequence. All commands issued during this time will
be ignored.
Note 10: Guaranteed by design.
Note 11: All channels active at V

, unloaded. Static logic inputs with V

and V
IH
= V

.
Note 12: An unconnected condition on the ADDR_ pins is sensed via a resistive pullup and pulldown operation; for proper
operation, ADDR_ pins should be tied to V
DDIO
, GND, or left unconnected with minimal capacitance.
