The potentiometer portion of a mixed-signal, digitally programmable potentiometer adds variability to an analog circuit, and its digital controls provide programmability. You can use a digital ...

A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our everyday applications. This article is about ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...

Download the full article as a .PDF, sponsored by Analog What are digital potentiometers, and how are they used? Digital potentiometers are integrated circuits that implement a resistive ladder and a ...

Digital potentiometers with internal non-volatile memory can provide the benefit of powering-up a switched-mode power supply with an accurate, predefined output voltage. To accomplish this, designers ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state potentiometer.

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits ...

Microchip announces the MCP4141/2 and MCP4241/2 non-volatile digital potentiometers. The new 7- and 8-bit devices have an SPI interface and are specified over an extended temperature range of -40 to ...

The DP4 Series digital potentiometer is for ac and dc drive systems needing precise, repeatable speed setting and digital readout. The DP4 supports bipolar connections with power supplies of ±10 Vdc ...

In 2024, Non-Volatile Digital Potentiometers dominated the market with a share of 66.2%, as they can retain any desired resistance setting even during a power loss, making them critical components in ...
