Several microcontroller applications utilize a digital-to-analog converter. Though many of these applications require a complex DAC, some may only need a simple single-channel DAC. Because most MCUs ...

This application note reviews a circuit technique that is used to create an analog signal output using Pulse Width Modulation (PWM). The paper explains the theory and provides some circuit examples.

This article describes a simple technique for using a processors PWM output to produce an analog control voltage that matches the load’s input range, thus maximizing control resolution. Most ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Zenith has come out with an affordable digital-to-analog TV signal converter box, the DTT900. The box, which makes it debut at this week’s Consumer Electronics Show in Las Vegas, takes the digital TV ...

This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...
