is tested in the circuit of Figure 1. ICL7107 is tested in the circuit of Figure 2.
Note 4: See the Differential Input section.
Note 5: Backplane drive is in phase with segment drive for “off” segment, 180N out of phase for “on” segment. Frequency is 20
times the conversion rate. Average DC component is less than 50mV.
