NOTES: A. The conversion cycle, which requires 36 system clock periods, is initiated with the eighth I/O CLOCK
↓ after CS↓ for the channel
whose address exists in memory at that time.
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.
C. To minimize errors caused by noise at the CS input, the internal circuitry waits for three system clock cycles (or less) after a chip
select transition 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.
