Abstract
PURPOSE:To obtain an integrated circuit for outputting a deciding signal which can discriminate whether an output signal to an input signal is correct or erroneous by constituting said circuit so that a coincidence signal can be outputted from a comparing circuit when input and output signals of an amplifying circuit coincides. CONSTITUTION:The integrated circuit is provided with a comparing circuit 4 consisting of an exclusive OR circuit for comparing input and output signals of an amplifying circuit 2, and an FF circuit 5 for outputting an output signal synchronized by a comparison timing signal for correcting an erroneous output of the comparing circuit 4 caused by the amplifying circuit 2. In this state, when the input and the output signals of the amplifying circuit 2 coincides, a coincidence signal is outputted from the comparing circuit 4, and when the input and the output of the amplifying circuit 2 becomes a discrepancy, a discrepancy signal is outputted from the comparing circuit 4. Also, when the output signal of the amplifying circuit 2 is brought to output delay due to an external load capacity, etc., and the comparison of the input and the output signals of the amplifying circuit 2 becomes a discrepancy, it is corrected by the FF circuit 5 and the coincidence signal is outputted.
