Accurate, Fast Settling Analog Voltages from Digital PWM
Signals
Design Note 538
Mark Thoren and Chad Steward
Introduction
Pulse width modulation (PWM) is a common technique
for generating analog voltages from a digital device such
as a microcontroller or FPGA. Most microcontrollers have
dedicated PWM generation peripherals built in, and it only
takes a few lines of RTL code to generate a PWM signal
from an FPGA. This is a simple, practical technique if
the analog signalвЂ™s performance requirements are not
too stringent, as only one output pin is required and the
code overhead is very low when compared to a digitalto-analog converter (DAC) with an SPI or I2C interface.
FigureВ 1 shows a typical application, with a digital output
pin that is filtered to produce an analog voltage.
