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 currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specifi ed.
Note 3: The 5V

Note 5: The device pulls up the V
Note 6: UHF package specifi cation limits are identical to G package limits
and guaranteed by design and by correlation to wafer test measurements.
Note 7: Guaranteed by design and not subject to test.
Note 8: Integral Nonlinearity is defi ned as the deviation of a code from a
precise analog input voltage. Maximum specifi cations are limited by the
LSB step size and the single shot measurement. Typical specifi cations are
measured from 1/4, 1/2, 3/4 areas of the quantization band.
