NOTES:
1. Input voltages may exceed the supply voltages provided the input current is limited to 100µA.
2.
JA
is measured with the component mounted on a low effective thermal conductivity test board in free air.
3. Unless otherwise noted, specifications apply to both the ICL7106 and ICL7107 at T

= 25°C, f
CLOCK
= 48kHz.
ICL7106 is tested in the circuit of Figure 1. ICL7107 is tested in the circuit of Figure 2.
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. Average DC component is less than 50mV.
5. Not tested, guaranteed by design.
