Welcome back to the Digilent Blog!<\/p>\n

You may have noticed awhile back that Digilent released a set of PowerBRICK<\/a>s, which, as the name implies, are powerful little components that can produce a variety of voltages all while being run right from the USB port on your computer.<\/p>\n

\"Digilent's
Digilent’s set of PowerBRICKs.<\/figcaption><\/figure>\n

Based on the PowerBRICKs labeled voltage (3.3V, 5V, 9V, or 12V) users may get a corresponding negative or positive voltage of the labeled value from the PowerBRICK. But while all of the positive voltages are commonly used in a variety of everyday applications, what can you use the negative voltage for?<\/p>\n

The biggest thing that this negative voltage supply that PowerBRICKs enable are differential analog circuits. Perhaps you have an operational amplifier that needs to swing between two voltage ranges around a 0V point or a bi-polar stepper motor<\/a> that you want to get as much torque\u00a0as you can from it.<\/p>\n

\"Op-Amps
Op-Amps can produce signals that oscillate around 0V.<\/figcaption><\/figure>\n

Take the Soda Can Theremin<\/a> demo for example. This project needed three different reference voltages: 5V, 0V, and -5V. The 5V version of the PowerBRICK\u00a0is able to provide all three of these voltages, as well as more than enough current \u2014 at least for this particular application.<\/p>\n

What sort of project do you think a PowerBRICK would be perfect for?<\/p>\n
