• Manufacturer: Maxim

TIMING CHARACTERISTICS
(VDDD = VDDA = +5V, VSSD = VSSA = -5V, unless otherwise noted.)
ELECTRICAL CHARACTERISTICS (continued)
(VDDD = VDDA = +5V, VSSD = VSSA = -5V, f
values are at T
Note 1: Accuracy and dynamic performance tests performed after calibration.
Note 2: Tested with 50% duty cycle. Duty cycles from 25% to 75% at 1.7MHz are acceptable.
Note 3: See
Note 4: Guaranteed by design, not tested.
Note 5: Measured in shutdown mode with CLK and SCLK low.
14-Bit, 85ksps ADC with 10µA Shutdown
Note 6: Settling time required after deasserting shutdown to achieve less than 0.1LSB additional error.
