The Summing OPAMP Amplifier
https://www.electronics-lab.com/article/the-summing-opamp-amplifier/
Introduction In most of our previous tutorials concerning operational amplifiers, only one input was applied to either the inverting or non-inverting op-amp’s input. This new article will deal with a configuration known as the summing amplifier which gives an output that is proportional to a weighted sum of the multiple inputs present. The inputs can […]

US-based technology Product development company, Earth People Technology, recently announced the launch of a DAC (digital to analog converter) breakout board that is based on the popular eight-bit MCP4901 DAC Chip. The new breakout board, in line with the nature of the products developed by the company, comes with breadboard compatibility which makes it easy […]
Audio DAC for Raspberry Pi
https://www.electronics-lab.com/audio-dac-raspberry-pi/
Small single-board computers like the Raspberry Pi are ideal for use as small stand-alone network audio players. With Volumio and other specialized Linux distributions, putting together an audio player is remarkably easy. And as Elektor staff member Ton Giesberts shows in the referred article, you can also use this approach to build a high-end audio […]
3V DACs used in ±10V applications
https://www.electronics-lab.com/3v-dacs-used-%c2%b110v-applications/
Boosting DAC’s output to drive larger voltage tackled in this app note from MAXIM Integrated. Many modern systems have the majority of their electronics powered by 3.3V or lower, but must drive external loads with ±10V, a range that is still very common in industrial applications. There are digital to analog converters (DACs) available that […]

Arduino controlled Dual Mono AK4490 DAC (part 3)
https://www.electronics-lab.com/arduino-controlled-dual-mono-ak4490-dac-part-3/
Here’s the part 3 of Dimitris’ Arduino controlled Dual Mono AK4490 DAC project. If you missed part 1 and part 2, check them out. Following up on Part 2, it’s time to talk about the output stage. This output stage is the brainchild of my friend Kostas, all I did was lay out the PCB. It […]
DAC Shield For Arduino Nano using MCP4725
https://www.electronics-lab.com/dac-shield-arduino-nano-using-mcp4725/
This project features an easy to use Digital to Analog converter (DAC) shield for Arduino Nano. The project is built using MC4725 12Bit DAC IC over I2C communication. The shield directly seats on Arduino Nano and also can be used as stand-alone DAC converter that can be connected to other micro-controller board with help of […]
10 or 12-bit DAC from the ATtiny85
https://www.electronics-lab.com/10-12-bit-dac-attiny85/
David Johnson-Davies @ technoblogy.com writes: This article describes how to get up to two 10 or 12-bit digital-to-analogue outputs from an 8-bit Timer/Counter, such as in the ATtiny85. To test the routine I built a circuit which allows you to vary the brightness of two LEDs with two potentiometers: 10 or 12-bit DAC from the […]
Generating Analog Voltage with Digital Circuit
https://www.electronics-lab.com/generating-analog-voltage-with-digital-circuit/
Maurizio show us how to generate an analog voltage using a microcontroller and some resistors. The purpose of this article is how to generate analog voltage with digital circuit. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the schematic has a negative impact on the […]
