The ISL23328 is a volatile, low voltage, low noise, low power, 128-Tap, dual digitally controlled potentiometer (DCP) with an I2C Bus™ interface. It integrates two DCP cores, wiper switches and ...

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 ...

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 ...

One of our favorite purveyors of electronics knowledge is at it again. This time, [Afroman] explains how frequency modulation works while building up a short-range FM transmitter on a board he has ...

Download this article in PDF format. High-brightness visible-light LEDs (VLEDs) require a constant-current source. This simple, RFI-free circuit takes advantage of the normally-on properties of the ...
