Datasheet

MAX5703/MAX5704/MAX5705
Ultra-Small, Single-Channel, 8-/10-/12-Bit Buffered Output
Voltage DACs with Internal Reference and SPI Interface
8Maxim Integrated
Note 2: 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 3: DC Performance is tested without load.
Note 4: Linearity is tested with unloaded outputs to within 20mV of GND and V
DD.
Note 5: Gain and offset calculated from measurements made with V
REF
= V
DD
at code 30 and 4065 for MAX5705, code 8 and
1016 for MAX5704, and code 2 and 254 for MAX5703.
Note 6: Subject to zero and full-scale error limits and V
REF
settings.
Note 7: On power-up, the device initiates an internal 200Fs (typ) calibration sequence. All commands issued during this time will
be ignored.
Note 8: Specification is guaranteed by design and characterization.
Note 9: Static logic inputs with V
IL
= V
GND
and V
IH
= V
DDIO
.
Note 10: All timing is tested with V
IL
= V
GND
and V
IH
= V
DDIO
.
