D381A Datasheet, PDF (1/15 Pages) List of Unclassifed Manufacturers – Electroluminescent Lamp Driver IC

General Description:
The Durel^ D381A is part of a family of highly integrated EL
drivers based on Durel’s patented three-port (3P) topology, which
offers built-in EMI shielding. This high-performance device uses
a proprietary circuit design for programmable wave-shaping for
low-noise performance in applications that are sensitive to audible
and electrical noise.
