Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to digital ground with REF– and GND wired together (unless otherwise noted).

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). The device is functional with reference voltages down to 1 V (Vref+ – Vref–); however,
the electrical specifications are no longer applicable.
3. To minimize errors caused by noise at CS, the internal circuitry waits for a setup time plus two falling edges of the internal system
clock after CS
↓
before responding to control input signals. Therefore, no attempt should be made to clock in an address until the
minimum CS setup time has elapsed.
4. For 11- to 16-bit transfers, after the tenth I/O CLOCK falling edge (
≤
2 V) at least 1 I/O CLOCK rising edge (
≥
2 V) must occur within
9.5
μ
s.
5. This is the time required for the clock input signal to fall from VIHmin to VILmax or to rise from VILmax to VIHmin. In the vicinity of
normal room temperature, the devices function with input clock transition time as slow as 1
μ
s for remote data-acquisition
applications where the sensor and the A/D converter are placed several feet away from the controlling microprocessor.
