Supertex HV881DB1
16-Channel EL Lamp Driver Demoboard
Supertex HV881DB1 16-Channel EL Lamp Driver Demoboard contains the necessary circuitry to demonstrate the features of the 16 channel EL lamp driver board HV881. In order to drive the EL lamps, an I2C interface needs to be provided to the board along with a power supply. The Supertex HV881DB1 16-Channel EL Lamp Driver Demoboard has been optimized to drive 16 EL lamps, each of size 0.15in2 (approx capacitance 500pF). Each of the EL lamps' brightness can be controlled independently using the I2C interface.
