How-to use PWM to Generate Analog (or Analogue) Voltage in Digital Circuits

Many times, designers are faced with the need of generating analogue or analog voltage levels in purely digital circuits. 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 overall cost of the system. 1. Introduction In the first part of this article (Generating Analog Voltage with Digital Cir ...

Generating Analog Voltage with Digital Circuit

he 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 overall cost of the system. There are however, cheap methods of creating the required voltage levels, and even of generating pseudo-analogue signals, using pure ...

Analog Devices AD587 10V Reference

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 reference chip. AD587KN 10V precision referenceThis model of chip has an output value ...

Trinket Powered Analog Meter Clock

Overview Trinket lends itself very well to building clock projects, its small and easy to hide behind a larger display. And clocks don't need a lot of logic, this example only has maybe 20 lines of code. Adding a digital display via I2C is possible using seven segment or character-based displays (with the library code posted for other projects). This project interfaces Trinket to the the Adafruit DS1307 rea ...

Optical module with LEDs, integrated IC, analog frontend and Cortex-M0 processor

The AS7000 solution contains the AS7000 module including the LEDs, photo-sensor, analog front end (AFE) and controller as well as application software required to implement an accurate optical HRM/HRV fitness band product. The module also enables skin temperature and skin resistivity measurements by providing interfaces to external sensors. The AS7000’s low-power design is particularly well suited to applic ...

MIDI-Controlled Analog Music Synthesizer

For my electrical engineering senior design project, I decided on designing a analog music synthesizer with MIDI control. I have to admit, this was what I wanted to do since high school and was my ultimate goal as a musician, artist, DIY person, and engineer. This project, in the end, will combine all of my knowledge into one nice little package that I get to show off to friends, family, and faculty and is ...
