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 GND (unless otherwise

noted).

will be clamped by internal diodes. This product can handle input currents

Note 4: When these pin voltages are taken below GND, they will be

clamped by internal diodes. This product can handle input currents of

sine wave, input range =

±1.6V differential, unless otherwise specified.

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: Bipolar offset is the offset voltage measured from – 0.5 LSB

when the output code flickers between 0000 0000 0000 and

1111 1111 1111.

Note 8: Guaranteed by design, not subject to test.

Note 9: Recommended operating conditions.
