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.

The design and optimisation of analog-digital converters (ADCs) and digital-analog converters (DACs) play a pivotal role in modern electronic systems, bridging the gap between the analog real world ...

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 ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

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 ...

Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...
