ELM412 - Piezo Element Driver
The ELM412 is an 8 pin oscillator circuit for driving piezo-electric elements.
With the exception of one external resistor, all of the circuitry required to drive a typical piezo ‘bender’ is contained within this chip.
This circuit allows the user to select one of eight possible operating frequencie

* Low power CMOS design
* Wide supply range - 3.0 to 5.5 volt operation
* No external timing elements required
* Generates eight common piezo frequencies
* Bridged output for greater audio power
* Modified waveform for reduced harmonics Connection Dia
