How To Connect & Power A Car Amp In Your Home + Diagrams
Option #2: Estimating amp current needed for higher power use. If you''re planning to use a car amp to drive speakers hard, you''ll need a lot of amperage, which you can estimate pretty closely. We also need to consider wasted power to come up with a final number. (All amps waste some power as heat and draw some additional current for that ...
Using an op-amp to drive LEDs according to an incoming signal
Finally, we make an op-amp does this magic thus obtaining a 1/2 of the OP''s circuit. Let''s see how the op-amp reacts at two different values of the LED voltage. VF = 1 V: The op-amp adjusts its output voltage equal to -1 V. simulate this circuit. VF = 3 V: The op-amp adjusts its output voltage equal to -3 V. simulate this circuit "Perfect ...
The right way to use instrumentation amplifiers
Its input-voltage range is similar. Under these conditions, the amplifier''s output swing almost equals the supply voltage. So, when using a 5V single supply, the amplifier has approximately a 4.49V output swing. Unfortunately, some designers forget about amplifier headroom and use standard, non-rail-to-rail products in these applications.

Car Audio Myth – You Can''t Ground a Car Audio Amplifier to the Battery
At low to moderate volume levels, our amplifier won''t draw much current. If the amp is a modern Class-D design, it will likely have a driver IC that includes low-voltage support for start-stop vehicles. If so, the amp won''t shut off even if the voltage drops below 6 volts for a moment. Let''s run the math again.

7 common mistakes to avoid with your stereo amplifier
If you do want to use digital, think about whether to go coaxial or optical if your source/amp pairing gives you the choice. Coaxial digital uses electricity to transmit audio, while optical uses laser light to transfer signals. In our experience, the former connection tends to sound slightly better and also has a greater bandwidth available, …

The right way to use instrumentation amplifiers
Instrumentation amplifiers find wide use in real-world data acquisition. However, designers often incorrectly apply them. Specifically, although modern in amps have excellent CMR (common-mode rejection), designers must limit the total common-mode voltage, plus the signal voltage, to avoid saturating the amplifier''s internal input buffers.
Increase Amplifier Output Drive Using a Push-Pull Amplifier …
In this circuit, we add the 2N3904 and 2N3906 NPN/PNP transistor pair in a push-pull configuration to increase output current. The 2N3904 40V, 200mA NPN transitor with a minimum beta (ß) gain of 80 (I C = 1mA, V CE = 1V). The 2N3906 is the complementary -40V, 200mA PNP transisitor also with a minimum beta (ß) gain of 80 (I C …
