Test Conditions
Note
1:
Input voltages may exceed the supply voltages, provided the input current is limited to ±100
A.
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.
5:
See “Typical Application”.
6:
During Auto-Zero phase, current is 10-20
A higher. A 48kHz ocillator increases current by 8A (Typical). Common
current is not included.
