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.
Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...
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 ...
NORWOOD, Mass.--(BUSINESS WIRE)--Analog Devices, Inc. (ADI), a global leader in high-performance signal processing technology and the data converter market share leader*, today introduced the AD9142 ...
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 ...
New AD9250 dual-channel, 14-bit, 250-MSPS, A/D converter with JESD204B-compatible output connects seamlessly to high-speed FPGAs and enables precise multi-channel converter synchronization. NORWOOD, ...
[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 ...
