CONDITIONS
(Notes 9, 10)
The q indicates specifications which apply over the full operating
temperature range; all other limits and typicals TA = 25°C.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All voltage values are with respect to ground with DGND, AGND1
and AGND2 wired together (unless otherwise noted).
Note 3: When these pin voltages are taken below ground or above VANA =
VDIG = VDD, they will be clamped by internal diodes. This product can
handle input currents of greater than 100mA below ground or above VDD
without latch-up.
Note 4: When these pin voltages are taken below ground, they will be
clamped by internal diodes. This product can handle input currents of
90mA below ground without latchup. These pins are not clamped to VDD.

Note 5: VDD = 5V, fSAMPLE = 100kHz, tr = tf = 5ns unless otherwise
specified.
Note 6: Linearity, offset and full-scale specifications apply for a VIN input
with respect to ground.
Note 7: Integral nonlinearity is defined as the deviation of a code from a
straight line passing through the actual end points of the transfer curve.
The deviation is measured from the center of the quantization band.
Note 8: Bipolar offset is the offset voltage measured from – 0.5 LSB when
the output code flickers between 0000 0000 0000 0000 and 1111 1111
1111 1111.
Note 9: Guaranteed by design, not subject to test.
Note 10: Recommended operating conditions.
