ICL7126
,
IN LO is tied to COMMON, thus establishing the correct common
mode voltage. COMMON acts as a pre-regulator for the reference.
Values shown are for 1 reading/sec.
Since low TC zeners have breakdown voltages ~6.8V, diode must be
placed across the total supply (10V). As in the case of Figure 12, IN
LO may be tied to COMMON.
