10 x LM331N LM331 ic DIP-8

hi welcome to another video tutorial from Robojax  in this video we are going to do test and review   this pulse modulator to voltage converter made  by IC station so their website is IC station   comm they send us this product for review and we  are going to do honest review and see how this   works in many industrial application or maybe  educational application you need to convert the   perfect modulation to the voltage so you want to  find the relationship between the two to maybe   control a motor or whatever you want to do so  this module will get a pulse width modulated   signal at an input and convert it to the voltage  and will give you the output so the input can be   video 0 to 100 percent duty cycle and pulse width  modulation and the output will be between 0 to 10   volts up to 10 volts so this is a module these two  points are for the input which can accept between   12 to
