Low Cost PWM to DAC Module

1, Low Cost , easy to reach high resolutions DAC (depended on the PWM resolutions)

2, The Accuracy only depended on the REF voltage accuracy

3, Add Precision digital to analog convertor in any low cost system with PWM signal

4, The output Full scale voltage is depended on the VREF

5, The PWM digital noise will not impact the analog output signal
