Previous Conversion Data A
NOTES: A. The conversion cycle, which requires 36 system clock periods, is initiated on the 8th falling edge of I/O CLOCK after CS goes low
for the channel whose address exists in memory at that time. If CS is kept low during conversion, I/O CLOCK must remain low
for at least 36 system clock cycles to allow conversion to be completed.
B. The most significant bit (MSB) will automatically be placed on the DATA OUT bus after CS is brought low. The remaining seven
bits (A6–A0) will be clocked out on the first seven I/O CLOCK falling edges.
falling edge is detected before responding to control input signals. Therefore, no attempt should be made to clock-in address data
until the minimum chip-select setup time has elapsed.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to digital ground with REF– and GND wired together (unless otherwise noted).
