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.

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 ...

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 ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...

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 ...

A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...
