NOTES:
3. Unless otherwise noted, specifications apply to both the ICL7106 and ICL7107 at T A = 25 o C, fCLOCK = 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.
6. Sample Tested.
