PURPOSE: A test device is provided to be able to test easily with a logic tester without purchasing options separately when an analog/digital converter and a digital/analog converter are tested. CONSTITUTION: The digital/analog converter test device comprises; three electric power sources such as VRH(Voltage Reference High) generator, VRL(Voltage Reference Low) generator and AIN(analog in); a digital/analog converter to convert an analog inputted voltage generating part into a memory, the waveform data stored in the memory into analog volume and generate a lamp voltage or a waveform. In this way, at the time of testing an analog/digital converter and a digital/analog converter, it can be done without getting an optional program separately.
