This Design Idea describes an analog voltage that controls a digital potentiometer through the device’s I 2 C interface. An ADC in the Microchip PIC12F683 microcontroller converts the analog voltage ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

Sunnyvale, Calif.—Maxim Integrated Products has introduced what it claims are the industry's lowest voltage digital potentiometers. This family of dual, 256-tap, volatile digital potentiometers ...

Input ranges are switch-selectable for 0-100 ohms through 0-1 Mohms. Input span is 10 to 100% of potentiometer range, while input offset can be set from 0 to 90% in 10% increments. Output can be ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

The newer a piece of farm equipment, the more likely some aspect of it needs to be calibrated, and sometimes re-calibrated, for it to work correctly. In case. you’ve ever wondered, here’s what ...
