A common problem for digital potentiometers (DigiPots) is the effect of wiper resistance, which produces quite noticeable non-linearities of regulation at both ends of the resistance range. These ...
Xicor Introduces the First Dual Twin-Wiper 256-tap Digitally Controlled Potentiometer – X9455 Series
MILPITAS, Calif.–July 17, 2003–Xicor, Inc. (NASDAQ: XICO), a leading supplier of high-performance analog and mixed-signal integrated circuits, announced the first family of twin-wiper digitally ...
While almost always called "potentiometers" (which are technically defined as three-terminal variable voltage dividers), many "pots" actually end up being used as variable resistors (rheostats) ...
A three-wire bus is commonly used to control digitally controlled potentiometers (DCPs). One example of this type of bus is Xicor's 32-tap X9315 (U3), shown in the figure. This asynchronous bus has no ...
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 ...
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 ...
