NOTES:
2. Analog input voltages greater than that applied to REF+ convert as all ones (11111111), while input voltages less than that applied
to REF – convert as all zeros (00000000). For proper operation, REF+ must be at least 1 V higher than REF –. Also, the total
unadjusted error may increase as this differential reference voltage falls below 4.75 V.
3. 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
µs for remote data acquisition
applications where the sensor and the A/D converter are placed several feet away from the controlling microprocessor.
4. To minimize errors caused by noise at the chip select input, the internal circuitry waits for two rising edges and one falling edge of
the internal system clock after CS
↓ before responding to control input signals. The CS setup time is given by the tsu(CS)
specifications. Therefore, no attempt should be made to clock-in address data until the minimum chip select setup time has elapsed.
