those
listed
under
“Absolute
Maximum 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.

Note
1:
Input voltages may exceed the supply voltages, provided the input current is limited to ±100
μA.
2: Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
3: Refer to “Differential Input” discussion.
4: Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment. Frequency is
20 times conversion rate. Average DC component is less than 50mV.
6: During Auto-Zero phase, current is 10-20
μA higher. A 48kHz ocillator increases current by 8μA (Typical). Common
current is not included.
