New Piezo Sounder Driver for Bluetooth Location Trackers and Haptic Feedback Devices from Diodes

Diodes introduced a new 22VPP/31VPP selectable output piezoelectric sounder driver, for maximizing sound pressure level (SPL) delivery from a ceramic/piezo sounder. The PAM8907 has a built-in synchronous boost converter, which extends SPL in battery-powered systems and outperforms other similar sounder drivers. The device is optimized for use in wireless trackers, alarm systems, domestic appliances, or ultrasonic related piezo driver applications and haptic feedback.

A connected smoke alarm that's also a speaker, strategically placed in the ceiling to cover any room with quality sound. The idea might sound bizarre at first, but indeed it reflects the way manufacturers are reimagining different categories in the era of "smart devices." Following a successful presentation at CES 2018, First Alert launched its Onelink Safe & Sound Connected Smoke Alarm with Amazon Alexa, allowing users to ask questions or and even listen to music.
