Class B devices do not pass current when the output device is idle. Class AB audio amplifier chips combine Class A and Class B operation. Class C designs are used for radio frequency (RF) transmission ...

Class D audio amplifier chips are a type of amplifier that uses switching technology to convert an input audio signal into a high-frequency pulse-width modulated (PWM) signal. These amplifiers are ...

A recent design by [Selenium] is super simple because it uses a single LM386 audio amplifier IC. You might be surprised that you can convert an audio amplifier to a receiver using just a handful ...

There are a lot of better audio amplifier chips these days if you’re looking for lower voltages. Cellphones and lithium-ion batteries, along with the overall trend toward lower voltages in ...

iFi Audio says the ZEN Blue 3 has audiophile-grade circuitry instead of a System-on-a-Chip design. This means there are separate Bluetooth, DAC and Op-Amp chips for improved sound quality.
