General Description
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.
Key Features
- 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 Diagram PDIP and SOIC (top view) VDD F2 F1 F0 1 2 3 4 8 7 6 5 VSS Out1 Out2 Enable.
