Simple circuit provides precision ADC interface
Moshe Gerstanhaber @ edn.com provides an simple ADC interface using instrumentation amplifier IC. Real-world measurement requires the extraction of weak signals from noisy sources. High common-mode voltages are often present even in differential measurements. The usual approach to...

Automatic monitor brightness controller
Dilshan Jayakody build a auto monitor brightness controller that adjusts your monitor brightness according to lighting conditions. He writes: The sensor unit of this system is build around PIC18F2550 8-bit microcontroller. To measure the light level we use LDR with MCU's inbuilt ADC....

DIY milliohmmeter
by hwmakers.eu: This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current...

TC7106 – 3 1/2 Digit ADC for LCD Display
The TC7106 3½ digit LCD direct-display drive analog-to-digital converter has a reference with a 80ppm/°C max temperature coefficient. TC7106 based systems may be upgraded without changing external passive component values to the TC7106A for a more precise system. High impedance...
