SM8140A NIPPON PRECISION CIRCUITS INC. EL Driver IC OVERVIEW The SM8140A is designed for using as EL (Electronic 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 current, low supply voltages, low operating supply currents, simple brightness control and low EMI (Electro-Magnetic Interference) emission due to the inherent smooth driver wave forms.
