Re: square to sine ... I want to drive a coil using a sine wave.I used to use a 5th order filter from Maxim for the conversion of square wave(1khz which is generated by the PIC micro) to sine wave.But that filter works fine but it also needs 125khz to convert 1khz square wave into 1KHZ sine wave.So i used to generate 1KHZ and 125khz square wave from the pic and then feed these waves into the filter and then the output from the filter will be a pure 1KHZ sine wave which is then used to drive the coil in one of my applications.But now the problem is that this takes too much of the processor power .So i am looking for a an alternative solution or a circuit where i can feed my reference signal from the PICwhich theron converts the 1khz square wave into 1khz sine wave. ...
