IV. Wave-Shape Selection
The D381A driver IC uses a patented wave-shaping technique for reducing audible noise from an EL lamp. The linear
discharge of the output waveform may be adjusted by selecting a proper value for R. The optimal discharge level for
an application depends on the lamp size, lamp brightness, and application conditions. To ensure that the D381A is
configured optimally, various levels should be evaluated. In many cases, the lower discharge levels result is lower
audible noise from the EL lamp.

Typical waveshapes corresponding to the various discharge levels for a 4in2 lamp are shown below. The waveshape
with the smoothest transition slope in the discharge portion of the waveform yields the lowest audible noise.
