Figure 14. EL lamp brightness increases with
increasing bias supply voltage.
Figure 13. Overall supply current increases almost
linearly with increasing bias supply voltage.
Figure 15. Lamp frequency remains stable over the
operating temperature range for a fixed set of circuit
conditions.
Figure 17. Circuit supply current is very stable of the
typical operating range.
Figure 16. Lamp peak voltage remains relatively
constant over the typical operating temperature range.
