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 ground.
Note 3:
When these pin voltages are taken below ground or above REF or
OV
DD
, they will be clamped by internal diodes. This product can handle
input currents up to 100mA below ground or above REF or OV
DD
without
latchup.

Note 5:
Recommended operating conditions.
Note 6:
Integral nonlinearity is defined 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:
Guaranteed by design, not subject to test.
Note 8:
Bipolar zero-scale error is the offset voltage measured from –0.5LSB
when the output code flickers between 0000 0000 0000 0000 0000 0000
and 1111 1111 1111 1111 1111 1111. Full-scale bipolar error is the
worst-case of –FS or +FS untrimmed deviation from ideal first and last code
transitions and includes the effect of offset error.
Note 9:
All specifications in dB are referred to a full-scale ±5V input with a
5V reference voltage.
