How Piezo Sounder Drivers Increase Sound Pressure Levels Across a Wider Battery Voltage Range

Piezo sounders create warning or alert noises in many applications, oftentimes in portable, battery-powered, and space-saving products. These devices consist of a ceramic element attached to a metal plate, where the ceramic element uses the piezoelectric effect to distort its shape when a voltage is applied. As it contracts and expands due to the varying voltage, the attached plate vibrates audibly.

Crystal oscillators: bringing synchronization to digital electronics

The majority of electronics systems encountered at home or work will comprise at least one oscillator working as a clock that delivers accurate timing, synchronizes operations or acts as a frequency reference. Here, we’ll be looking at the many benefits of using quartz crystal oscillators and discussing the choices available.

BoM and PCB Space Savings Achieved with Control Channel Aggregation for Optical Interfaces

Fibre optic networks bring the promise of fast broadband to new customers all around the world. It increasingly reaches new limits, but to provide a guaranteed level of service, that bandwidth must be managed effectively. A significant factor to that effectiveness is how it interfaces with other network equipment running over copper cable.

Transient Voltage Suppression in Automotive

In automotive applications, it’s essential to protect sensitive semiconductor components against power surges, transients and electrostatic discharge (ESD). A single transient voltage spike could easily damage or disrupt a component, while electrical noise of even relatively low energy can cause significant interruption to digital communications.

Improving Power Conversion Efficiency with Super Barrier Rectifiers

For the design of almost any electronics or electrical system, it’s important to maximise power efficiency. In mobile devices, better power efficiency delivers longer battery life, which is a key selling point. For basically any application, improving power efficiency means that size and weight can be reduced, and thermal management simplified – thus reducing costs. Of course, using less power also helps products to meet energy rating requirements, which may be a legal requirement, and an attractive feature for customers.
