*Stresses above those listed under "Absolute Maxi-
mum Ratings" may cause permanent damage to the
device. These are stress ratings only and functional
operation of the device at these or any other conditions
above those indicated in the operation sections of the
specifications is not implied. Exposure to Absolute
Maximum Rating conditions for extended periods may
affect device reliability.

1: Integrate time ≥ 66msec, auto zero time ≥ 66msec, VINT (peak) ≈ 4V.
2: End point linearity at ±1/4, ±1 /2, ±3/4 F.S. after full-scale adjustment.
3: Roll-over error is related to CINT, CREF, CAZ characteristics.
