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 10µs of the ris-
ing edge of CONVST, and have a minimum clock frequency of 100kHz.
