MAX5723/MAX5724/MAX5725
Ultra-Small, Octal-Channel, 8-/10-/12-Bit Buffered
Output DACs with Internal Reference and SPI Interface
8Maxim Integrated
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, V
REF
= V
DD
.
Note 5:
Linearity is tested with unloaded outputs to within 20mV of GND and V
DD
.
Note 6:
Gain and offset calculated from measurements made with V
REF
= V
DD
at codes 30 and 4065 for MAX5725, codes 8 and
1016 for MAX5724, and codes 2 and 254 for MAX5723.
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
for all inputs.
