This application note discusses the Avago Technologies AT-32063 dual low noise silicon bipolar transistor. The AT-32063 consists of two AT-320XX transistors mounted in a single package with all ...

This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

Reading an article about the first transistorized Hi-Fi amplifier, [Netzener] got the itch to make one. But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit.

These two circuits provide ripple rejection for unregulated power supplies to audio amplifier applications and can follow a declining voltage source (such as a battery) to low values without dropout.
