SP4415 - Electroluminescent Lamp Driver with Selectable Level Outputs
The SP4415 is a single chip DC-AC converter ideally suited for driving electroluminescent panels to four intensity levels.
The SP4415 is capable of converting DC input voltages as low as 2.2V into any of four AC voltage levels which can be set via external switch.

SP4415 Features
* high impedance (50 MΩ), low capacitance (2.5pF) and 200mV sensitivity. The external clock should range from (VDD-1V) to ground. The SP4415 is optimized for 32,768Hz clock signals and is allowed to vary from 20 kHz to 60kHz. The externally supplied clock signal provides the circuit with a clock sourc
