This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...

Audio is an integral part of portable consumer electronic devices. An integrated headphone audio power amplifier helps amplify the low-power baseband audio signals to drive crisp and clear audio when ...

[Debraj] needed a simple signal generator for a project he was working on, but didn’t have one handy. He found that the easiest and cheapest way to get clean, reliable signaling was by using something ...

If these signals exhibit a simple, periodic waveform, such as with sine, square, or triangular waves, the generators are called function generators. They are often used to check the function of ...

This “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Audio amplifier products are becoming more and more advanced in ...

In high-end audio equipment, careful selection of resistors is one of the best ways to avoid or minimize noise and distortion in the signal path. This paper describes the noise generation in resistors ...

International Solid-State Circuits Conference in San Francisco always seems to make space for audio amplifier developments, and this year is no exception, with some extraordinary distortion and noise ...

Analog Devices has created a pair of 22V stereo Class-D audio amplifier that idle at 6mA and shut-down to microamps. MAX98415A and MAX98425A are similar, and both including envelope tracking control ...
