This is a headphone amplifier project for audio digital-to-analog converters (DACs) with differential voltage outputs. This circuit converts the differential voltage output of the DAC to a single-ended, ground-referenced signal and provides the additional current necessary for...

Remember those good old days when everyone had those giant sound systems in their living room? Besides the inconvenience of the CDs, the sound experience was extremely fun, and they're always was a small star in the show: the small screen with the VU animations. Unfortunately, they fell...

Did you ever make a project and wanted to output a sound that was more than just a beep? Or maybe you wanted to play a long song on repeat, such as an audio alert for when something is not working on a factory, or just to annoy your friends, your choice. An Audio Programmable Indicator...

For a few years now, earbuds have been part of pop culture. It is slowly phasing out the earpiece and headphones. Most people make use of them because of the troubles associated with wired ear accessories, while others use it as a cool fashion accessory. Regardless of the reason you use...

This is an “Audio VU Meter” or “Sound Level Meter”, it is a general-purpose bar-graph Audio VU meter designed for fun projects. All you need is to hook up one wire to the output of the audio amplifier’s speaker pin along with GND and see the magic. The response of the circuit...

Good news for all audio enthusiasts: we are proud to present yet another all-analog circuit developed entirely in house. Despite the simple design of this audio power amp with just one pair of transistors in the output stage, Q-Watt can deliver over 200 quality watts into 4 ohms with...

M5Stack ATOM ECHO is a tiny programmable smart speaker. Its design is based on the M5ATOM series of products. The slim design has a dimension of 24x24 and is 17mm in height. Its premium finish gives it a professional look and makes it easy to carry anywhere. M5Stack ATOM ECHO can be...

The EVAL_AUDAMP24 e-mode GaN HEMT-based evaluation board from Infineon Technologies is a 2-channel, 225W/ch (4Ω at ±43V) or 250 W/ch (8Ω at ±63V) half-bridge class D audio power amplifier for high-end Hi-Fi audio systems. This evaluation board demonstrates how to use the IGT40R070D1...
