Power Amplifier Drives Multiple Inkjet Heads

Focus:

Beyond the familiar desktop applications, inkjet printers have commercial applications such as product packaging, billboards, and banners. In these applications, power op amp modules deliver the high-current pulses and high slew rates required to drive an array of piezo transducers. Design of the transducer drive circuit is described with special attention givem to heatsinking requirements.

What you’ll learn:

• How to drive piezoelectric transducers used in inkjet printing
• How to design piezoelectric transducer drive circuit using power op amp modules
• How to heatsink power op amps used to drive piezoelectric transducers
