IV. Wave-Shape Selection
The D371 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 one of 4 lamp discharge levels. The optimal discharge
level for an application depends on the lamp size, lamp brightness, and application conditions. To ensure that the D371
is configured optimally, each level should be evaluated. In many cases, the lower discharge levels result in lower
audible noise from the EL lamp.

Typical waveshapes corresponding to the various discharge levels for a small size lamp and a larger size lamp are
shown below. In each case, the waveshape with the smoothest transition slopes in the discharge portion of the
waveform yields the lowest audible noise.
