PROBLEM TO BE SOLVED: To reduce cost and the time taken for tests. SOLUTION: This apparatus for inspecting a digital-analog hybrid IC providing digital signal outputs and analog signal outputs comprises a means 24 for comparing a signal inputted to an input terminal with a reference value and a means 25 for determining the quality of the signal, based on the compared result by the comparing means. A digital signal from the digital-analog hybrid IC 1 is inputted directly to the input terminal of the comparing means and an analog signal from the digital-analog hybrid IC 1 is inputted to the input terminal of the comparing means through a correlation double sampling means 2.
