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 effect 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

Bipolar zero-scale error is the offset voltage measured from
–0.5LSB when the output code flickers between 00 0000 0000 0000 0000
and 11 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.
