  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 signal’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.
