Piezoelectric transducers are commonin ultrasonic and acoustic-alarm-signaling applications. To getenough acoustic power from a piezoelectrictransducer, you must power thedevice with a frequency at or ...

Most touchscreen panels have a limited type of haptic feedback or none at all. This is also true for many types of handheld or wearable devices like watches, touchpads, keyboards, a mouse, etc. The ...

The PAM8904E driver, designed for piezo-based sounders (buzzers), has a multilevel boost converter and can drive the capacitive loads associated with these audio transducers. Sounders (buzzers) based ...

Ever hear of a piezo-optomechanical circuit? We hadn’t either. Let’s break it down. Piezo implies some transducer that converts motion to and from energy. Opto implies light. Mechanical implies…well, ...

Texas Instruments TXN launched ultrasonic lens cleaning semiconductors named the ULC1001 digital signal processor and companion DRV2901 piezo transducer driver. Featuring a proprietary technology, the ...
