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.
