The MAX4990 evaluation kit (EV kit) provides a proven
design to evaluate the MAX4990 high-voltage, ±15kV
ESD-protected electroluminescent lamp driver. Alligator
clip leads contact a wide variety of standard electrolu-
minescent lamps.
The MAX4990 EV kit printed-circuit board (PCB) comes
with a MAX4990ETD+ installed.
19-2472; Rev 0; 12/07
+ Denotes lead-free and RoHS-compliant.
