NOTES:
2. To minimize errors caused by noise at CS, the internal circuitry waits for three system clock cycles (or less) after a chip select falling
edge or rising 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.
3. Analog input voltages greater than that applied to REF+ convert as all “1”s (11111111), while input voltages less than that applied
to REF– convert as all “0”s (00000000). As the differential reference voltage decreases below 4.75 V, the total unadjusted error tends
to increase.
4. This is the time required for the clock input signal to fall from VIH min to VIL max or to rise from VIL max to VIH min. In the vicinity
of normal room temperature, the devices function with input clock transition time as slow as 2
μ
s for remote data acquisition
applications where the sensor and the A/D converter are placed several feet away from the controlling microprocessor.
