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.
Defined as the change in positive full scale caused by ±5% variation in the nominal supply voltage.
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 10μs of the ris-
ing edge of CONVST, and have a minimum clock frequency of 100kHz.
