7Maxim Integrated
MAX5713/MAX5714/MAX5715
Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and SPI Interface
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 MAX5715,
code 8 and 1016 for MAX5714, and code 2 and 254 for MAX5713.
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
FS
, unloaded. Static logic inputs with V
IL
= V
GND
and V
IH
= V
DDIO
.
Note 12: Daisy-chain speed is relaxed to accommodate (t
CRF
+ t
CSS0
) with margin (derived specification, not production tested).
Note 13: This specification and its propagation through the chain limits how quickly an aborted daisy-chain command can be fol-
lowed by another daisy-chain command, to be applied on a per-device basis.
