SM8140A
NIPPON PRECISION CIRCUITS INC.
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.
FEATURES
■
Specially providing EL driver functions
■
Non-transformer for compact outline
■
Bipolar driving for high power efficiency
■
Very low noise smooth driver wave forms
■
Brightness control with driving frequency change
(An external resistance determines the driving frequency)
■
Low power consumption by quiescent current
control
■
ON-chip high voltage output MOS transistor
