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

latch-up.

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: Zero-scale error is the offset voltage measured from 0.5LSB

when the output code flickers between 00 0000 0000 0000 0000 and

00 0000 0000 0000 0001. Full-scale error is the deviation of the last code

transition from ideal and includes the effect of offset error.

Note 8: All specifications in dB are referred to a full-scale 5V input with a

5V reference voltage.

Note 10: Guaranteed by design, not subject to test.

100MHz for rising capture.
