Reducing parts count and speeding design cycles, the TPA2008D2 clocks in as the first 5V Class D audio power amplifier that requires no filter and integrates a dc volume control. Gain is controlled by ...
In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
A simple stereo audio amplifier is built around two 7905 negative-voltage regulators (IC1 and IC2) and a few discrete components. The circuit will also work with other 79XX regulators if appropriate ...
