• Study of the circuit diagram and performance of a 4-bit weighted resistance type D/A converter. The digital inputs are to be given by operating four mechanical switches and the output read on the digital panel meter provided.
• The above experiment is conducted on a 4-bit discrete component R-2R network based unit.
• Manual operation of a 10-bit IC D/A converter type AD7533 through 10 mechanical switches. Due to a much better resistance matching in the integrated circuit, the performance is seen to be far superior compared to the discrete 4-bit circuits.
• Operation of the IC based circuit through the microprocessor kit provided. Some typical waveform generation exercises are suggested and solutions are provided. More problems can be attempted by the student with help from his supervisor.
