NOTES:

3. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.

4. Unless otherwise noted, specifications apply to both the ICL7106 and ICL7107 at TA = 25oC, fCLOCK = 48kHz. ICL7106 is tested in the

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

5. 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.

6. Not tested, guaranteed by design.

7. Sample Tested.
