Phoenix, Ariz. – The CAT5140 digital potentiometer from ON Semiconductor is a 256-tap, single-channel linear-taper digitally programmable potentiometer (DPP). The new device is a low-noise, reliable ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...

Digital potentiometers are digitally controlled variable resistors that can be used in place of their functionally equivalent mechanical counterparts. While digital potentiometers offer comparable ...

If you enjoy simulating circuits, you’ve probably used LTSpice. The program has a lot of powerful features we tend to not use, including the ability to make custom components that are quite complex.

What signal conditioning circuit could possibly be easier or more straightforward to design than a dual-channel dc amplifier with a common tracking-gain control? Of course, the obvious way to realize ...

A potentiometer is a three-terminal resistor with a rotating (as in this instrument) or sliding contact that forms an adjustable voltage divider. This example has a front bearing plate of gold-colored ...
