Data Sheet

D381A

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.
