Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All voltage values are with respect to GND.
Note 3: When this pin, A

greater than 100mA below GND or above V

Note 5: Integral linearity is defi ned as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve. The
deviation is measured from the center of the quantization band.

Note 7: Typical RMS noise at code transitions.
Note 8: Guaranteed by characterization. All input signals are specifi ed with
t
Note 9: All timing specifi cations given are with a 10pF capacitance load.
With a capacitance load greater than this value, a digital buffer or latch
must be used.
Note 10: Minimum f
Note 11: The time required for the output to cross the V
Note 12: Guaranteed by design, not subject to test.
Note 13: High temperatures degrade operating lifetimes. Operating lifetime
is derated at temperatures greater than 105°C.
