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
5: See “Typical Application”.
6: During Auto-Zero phase, current is 10-20μA higher. A 48kHz ocillator increases current by 8μA (Typical). Common
