Abstract
An output stage control circuit comprises an output driving means connected to a load for driving the same, a control means for taking out detection signals corresponding to signals flowing to the load and supplying analog control signals to the output driving means and a reference signal supply means for supplying reference signals to the control means, in which the analog control signals are generated depending on the detection signals and the reference signal, and the load is driven in an analogous manner by the output driving means depending on the analog control signals. The output stage control circuit can continuously supply the current to the load thereby operating the load stably with less occurrence of noises and stably for a long period of time.
