Digital Potentiometers (DigiPots)

Digital Potentiometers (Digipots) are digitally controlled electronic components that mimics the analog functions of a potentiometer. It is often used for trimming and scaling analog signals by microcontrollers. It is either built using an R-2R integrated circuit or a Digital-to-analog converter. A digital potentiometer is an electronic component that is often controlled by digital protocols […]

In Digital System Board Design, It is suggested to Tie high or low all the CMOS floating and unused inputs. Leaving inputs floating causes gate puncture (gates goes to intermediate logic creating a low resistance path to the ground thereby damaging the device). It is recommended to tie the TTL unused inputs to logic low […]

Resistance Temperature Detectors (RTD sensors) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. Resistance Temperature Detectors, as the name implies, are sensors used to measure temperature by correlating the resistance of the RTD element with temperature. RTD Sensors are also called as Resistance Thermometers, Resistive Thermal Devices. As […]

Surface Mount Resistors or SMD Resistors are very small rectangular shaped metal oxide film resistor. They have a ceramic substrate body onto which is deposited a thick layer of metal oxide resistance. The resistive value of the resistor is controlled by increasing the desired thickness, length or type of deposited film being used and highly […]
