ELM412 Datasheet Piezo Element Driver

Manufacturer: ELM

Overview: ELM412 Piezo Element Driver.

Datasheet Details

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 frequencies by way of three logic level inputs.

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.
