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 ...

What are digital potentiometers, and how are they used? Digital potentiometers are integrated circuits that implement a resistive ladder and a digital means of addressing a particular tap on the ...

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 ...

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 ...
