IMP803
Test and Application Circut, 6.0V
At higher input voltage levels, the IMP803 will drive large EL
lamps. Figure 3 shows a 6.0V circuit configuration that will drive
a 10 square-inch lamp.

Enable/Disable Operation
Figure 4 shows that the IMP803 can be enabled via a logic gate that
connects RSW to VDD, and disabled by connecting it to ground.
