Best gaming motherboards in 2021

The best gaming motherboards from the top Intel and AMD chipsets. The best gaming motherboards from the top Intel and AMD chipsets. (Image credit: Future)JUMP TO: Intel Z490Intel B460Intel Z390AMD X570AMD B550AMD A520 At the center of any amazing gaming PC is the motherboard. It’s the backbone of your rig that fits in all the key components you need in order to play all of your favorite games. Choosing the best motherboard for your system determines the size of the case you’ll use, what your storage options are, and what your CPU upgrade options are further down the line, among other things, so choosing the best motherboard is key to a problem-free build.  Even though there’s not much difference between motherboards built around the same chipset these days, it’s still important to get the motherboard that is right for you and for what you have in mind. These days it’s more…

Do You Need an Analog Comparator in Your MCU?

This industrial computer can benefit from an MCU with an integrated analog comparator. I remember when I built my first op-amp analog comparator in my college electronics classes using an LM358 op-amp. Such simple circuits don’t always seem to have practical use until you start designing them into real systems for your customers. An analog comparator is easy to build with positive feedback in an op-amp circuit, but you’ll always take up some space on the board with the op-amp IC and additional components in the feedback loop. What about working with an analog comparator and your MCU? Your MCU provides plenty of integrated functions and I/Os, and one option to accept a comparator output with your MCU is to use one of the GPIOs. A better option is to find an MCU with an integrated comparator circuit, which will eliminate the need for an external op-amp circuit or comparator…
