This car stereo booster uses an LM2896 IC which has two integrated amplifiers. It can be powered with voltages up to 15 volts. The power output is 2.5 watts per channel with an 8 Ω load and supply ...

One of the biggest problems for designers of op-amp circuitry arises when the circuit must be operated from a single supply, rather than ± 15 V. This application note provides working circuit examples ...

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 ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Professional speakers have two types of outputs identified as high and low level. The high-level outputs are used for the main speakers since they amplify the left and right speakers. Generally, the ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large output voltages on ...

A guaranteed way to make a receiver or amplifier fail is to create a short circuit by improperly connecting speaker wire to your speakers or receiver. It could be as simple as a stray strand of wire ...

In audio systems, the mixer provides a consistent signal that can be routed out to speakers, amplifier, recording equipment or headphones. A mixer signal is typically not amplified, or if it is, ...
