1. Input voltages may exceed the supply voltages provided the input current is limited to ±100µA.
2. θ
3. Unless otherwise noted, specifications apply to the ICL7136 at T
4. Back plane drive is in phase with segment drive for “off“ segment, 180 degrees out of phase for “on“ segment. Frequency is 20 times conversion rate.
5. Not tested, guaranteed by design.
6. 48kHz oscillator increases current by 20µA (Typ).
