Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
Integral nonlinearity is defined as the deviation of a code from a may cause permanent damage to the device. Exposure to any Absolute straight line passing through the actual endpoints of the transfer curve. Maximum Rating condition for extended periods may effect device The deviation is measured from the center of the quantization band. reliability and lifetime.
Note 7:
Bipolar zero-scale error is the offset voltage measured from
Note 2:
All voltage values are with respect to ground. –0.5LSB when the output code flickers between 0000 0000 0000 0000 and

When these pin voltages are taken below ground or above REF or 1111 1111 1111 1111. Full-scale bipolar error is the worst-case of –FS OV or +FS untrimmed deviation from ideal first and last code transitions and DD, they will be clamped by internal diodes. This product can handle input currents up to 100mA below ground or above REF or OV includes the effect of offset error. DD without latch-up.
