Voltage references are a humble piece of hardware, their sole function is to provide a stable, known voltage. This constant, known value of voltage can then be used as a reference for ADCs and DACs as well as provide a precision current source. I recently got hold of an Analog Devices AD587KN high precision 10.000V […]

With summer arriving, and the fear of dried out chicken looming, we wanted a more high tech way to track the temperature of items we are grilling outside. There are wireless probe thermometers, but they require carrying around a separate readout. We wanted a way to read the temperature from our smartphone, so we took

Three major power supply (Figure 1) architectures are defined for any engineer: 1.Linear Regulators. 2.Pulse width modulated switching (PWM). 3.High resonant technology switching. Some important parameters can described in the followig texts: Inputs: Vin(low), Vin(high) – minimum and maximum allowed input voltages, hence input voltage range. Iin(max) – maximum average input current. Outputs: Vout(min), Vout(max)

This Design Idea gives two versions of an indicator light that changes from green to red as a battery discharges. There are many circuits that do this sort of thing, but all the ones I have seen are too complex and costly for my taste. This DI shows a method that uses an absolute minimum

DISCLAIMER: This is an extremely dangerous project, and it should only be attempted by people with experience in electronics, and specifically, High Voltage. If it’s your first time seek help for your own safety. Homemade High Voltage supplies are unlikely to meet any international standards, the safety and correct operation is NOT guaranteed at all,

Such is the popularity of DC-to-DC voltage converters (“switching regulators”)––due to their high efficiency across wide input- and output-voltage ranges––that chip makers have focused a lot of research dollars on squeezing the essential components of the devices into modules. These modules typically include pulse-width-modulation (PWM) controllers and switching elements in a single, compact package, easing
0-10V_Monitor_PIC This project is a 0-10V Voltage Monitor. Description 0-10V Volt monitor project has been designed around LM3914 IC, It is an easy and less expensive project which instantly visualizes voltage level. The project is based on the popular LM3194 IC from Texas instruments. Handy 0-10V DC Voltmeter can be used as a voltage tester.

A family of pin-compatible synchronous step-down switching regulators with integrated power switches, the MIC28511/12/13 from Micrel, supplies up to 4 A of output current (MIC28513) and accepts a wide input supply range of 4.6 V to 70 V (MIC28512). The devices have an operating junction temperature range of -40°C to +125°C and come in very
