D371A Datasheet, PDF (1/14 Pages) List of Unclassifed Manufacturers – Electroluminescent Lamp Driver IC

General Description:
The Durel^ D371 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.
