Norwood, Mass.—Analog Devices Inc. (ADI) has introduced a digital potentiometer (digiPot) family with what it says offers the industry's best resistor tolerance, allowing designers of industrial and ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

Digital potentiometers are three-terminal resistors with an adjustable center connection. To set the output resistance, a digital signal is sent through an electrical interface. There are two main ...

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 ...

Linear potentiometers produce a resistance output that varies according to the displacement or position of a slider or wiper. They are variable resistors with three leads. Two leads connect to the ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...
