OVERVIEW
The SM8140A is designed for using as EL (Elec-
tronic Luminescence) sheet driver require very low
external parts counts, this result that very compact
and thin EL driver units can be made.
Also this device has the features to use in wider
range of applications demanding low quiescent cur-
rent, low supply voltages, low operating supply cur-
rents, simple brightness control and low EMI
(Electro-Magnetic Interference) emission due to the
inherent smooth driver wave forms.
