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 with DGND, AGND1

and AGND2 wired together (unless otherwise noted).

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

specified.

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.
