TIMING CHARACTERISTICS (Figures 3, 4, 5, 6 and 7) (Tables 1, 3) (continued)
Note 7:
Shutdown current is measured with analog input floating. The large amplitude of the maximum shutdown current specifi-
cation is due to automatic test equipment limitations.
Note 8:
Defined as the change in positive full scale caused by ±5% variation in the nominal supply voltage.
Note 9:
CONVST must remain low for at least the acquisition period. The maximum acquisition time is limited by internal capacitor
droop.
Note 10: CS-to-WR and CS-to-RD pins are internally AND together. Setup and hold times do not apply.
Note 11: Minimum clock frequency is limited only by the internal T/H droop rate. Limit the time between the falling edge of CONVST
to the falling edge of EOLC to a maximum of 0.25ms.
Note 12: To avoid T/H droop degrading the sampled analog input signals, the first clock pulse should occur within 10s of the ris-
ing edge of CONVST, and have a minimum clock frequency of 100kHz.
Typical Operating Characteristics
(AVDD = +5V, DVDD = +3V, AGND = DGND = 0V, VREF = VREFMS = +2.5V (external reference), see the Typical Operating Circuits sec-
tion, fCLK = 10MHz, 50% duty cycle, INTCLK/EXTCLK = AGND (external clock), SHDN = DGND, TA = +25°C, unless otherwise noted.)
