I am looking at using a CD4060 and 32.768Hz crystal, running off 4 x AAA cells, to produce a reference 16Hz sine wave. Required output is
5Vpp at 50ma to drive an optical array.We will need a quantity of these little circuits and prefer minumum component count and cost.
Is there a way to use a single transistor emitter follower and combine it with an RC smoothing filter to do the job?
The "sine wave" can be approximate, e.g. a well rounded square wave.
Any ideas would be appreciated. I considered uisng a phase shift oscillator, but prefer the option of multiple output frequencies the CD4060 affords.
