reasons for suggesting zener. ... less costly.
when the problem is "fluctuations" the elimination process requires that what is done to investigate one possible cause is guranteed to eliminate the potential cause that is being investigated. AFTER the last change (this can be a very long road) has been made and the output is stable "cost saving methods" can be tried. Use a 'voltage reference chip Erik PS cut out the irritating 'u' it is spelled 'you' unless you are entering your posts from a cellphone |
