    convert 5v PWM signal into analog signal ranges from -10 to +10 v

    hi folks
    I'm trying to do some custom servo motion control, for that purpose I need a basic circuit that converts the output signal from the controller that is 5v PWM and Direction digital output to analog signal ranges from -10v to +10v
    Example:
    PWM signal 90% and Dir 1 >> 9V output
    PWM signal 75% and Dir 0 >> -7.5v output

    I'll be very happy to see your suggestions

    with my step 2 linear,. you could control the analog amp with simple step/dir signals

    for the PWM signal, an opamp with lowpass filter, differential opamp with reference set to v/2 would do the job.

    You can buy such units off the shelf.
