Description The MAX98355A/MAX98355B are digital pulse-code modulation (PCM) input Class D power amplifiers that provide Class AB audio performance with Class D efficiency. These ICs offer five selectable gain settings (3dB, 6dB, 9dB, 12dB, and 15dB) set by a single gain-select input (GAIN). The digital audio interface is highly flexible with the MAX98355A supporting I²S […]

Just when you thought there were no unique selling points left in the world of LED light engines, Bridgelux releases a water-resistant series designed to future-proof outdoor luminaire manufacturing. Called Outdoor Lighting Module (OLM), it integrates LEDs, optics and environmental protection in a package that can be screwed to a heatsink, and is designed to
White lighting LEDs are almost universally a combination of a blue light-emitting InGaN die and a phosphor that steals some of the blue light and converts it into a broad spectrum peaking at yellow or amber. The combination of blue light and yellow light looks white to humans. But where do the phosphors come from?
Measuring performance of audio components like microphones, speakers, converters, and amplifiers can be a difficult task. In this post, I’ll talk about some of the tools I use to make this job easier. Analyzers, reference transducers, calibrators, meters, and more come with various feature sets and price tags. The items below just happen to be
It is possible to reconfigure radiation-hardened Xilinx FPGAs with the reliability required for space applications, writes a team of developers from Germany-based Fraunhofer IIS RF and microwave design department In 2017 the experimental Heinrich Hertz communications satellite (H2Sat) commissioned by the German Federal Ministry of Economics and Technology will be launched into space, to support
Lumileds has announced a lime green LED, revealing that it a key component in the ‘Hue’ range of colour tuneable LED replacement light bulbs from Philips (which owns Lumileds.

This application note presents fourteen EL driver circuits utilizing the Supertex HV823 and HV825 drivers. They have been optimized for a variety of applications and may be used as-is or used as a starting point in designing
After years of wondering when flexible displays would finally emerge, they jumped out at opposite ends of the size spectrum from Samsung and LG within a few months of each other. And they were all on show in Las Vegas earlier this month at the Consumer Electronics Show (CES). At the small end were bendable
