NOTES:
2. Analog input voltages greater than that applied to REF + convert as all ones (1111111111), while input voltages less than that applied
to REF – convert as all zeros (0000000000). For proper operation, REF + voltage must be at least 1 V higher than REF – voltage.
Also, the total unadjusted error may increase as this differential reference voltage falls below 4.75 V.
3. To minimize errors caused by noise at the chip select input, the internal circuitry waits for three system clock cycles (or less) after
a chip select falling edge is detected before responding to control input signals. Therefore, no attempt should be made to clock in
an address until the minimum chip select setup time elapses.
4. The amount of 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
s for remote data acquisition
applications where the sensor and the A/D converter are placed several feet away from the controlling microprocessor.
