NOTES:
2. Analog input voltages greater than that applied to REF + convert as all 1s (11111111), while input voltages less than that applied to
REF– convert as all 0s (00000000). 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 CS, 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 has elapsed.
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
s for remote data acquisition
applications where the sensor and the A/D converter are placed several feet away from the controlling microprocessor.
