ELECTRICAL CHARACTERISTICS (continued)
(VDDD = VDDA = +5V, VSSD = VSSA = -5V, fCLK = 1.7MHz, VREF = +5V, TA = TMIN to TMAX, unless otherwise noted. Typical
values are at TA = +25°C.)
TIMING CHARACTERISTICS
(VDDD = VDDA = +5V, VSSD = VSSA = -5V, unless otherwise noted.)
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
External Clock section.
Note 4: Guaranteed by design, not tested.
Note 5: Measured in shutdown mode with CLK and SCLK low.
