NOTES:

8. Unless otherwise noted, specifications apply to both the ICL7106 and ICL7107 at TA = +25°C, fCLOCK = 48kHz. ICL7106 is tested in the circuit of

Figure 1. ICL7107 is tested in the circuit of Figure 2.

9. 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.

10. Limit is not production tested. The maximum was established via characterization and/or design simulations.

11. Sample tested.
