Study Of Digital To Analog Converter

We offer Study of Digital-to-Analog Converter, DTA-01 useful for control labs. Measurement of the speed of a rotating shaft is a common requirement in many industrial and laboratory applications. Stroboscope, is a convenient-to-use, direct reading speed measuring instrument. A highly stable function generator IC based circuit provides the basic variable frequency timing pulses.
These are read on an IC based LCD/LED counters with direct speed display in rpm. The flasher unit generates the high intensity flashes at a suitably scaled rate directed towards the rotating shaft. Precision potentiometer's makes the task of speed setting very precise. The portable model, fitted into a light weight and strong plastic body is more suited for industrial / class room environment.
>> Highlights:-
Basic 4-bit weighted resistance
4-bit R-2R network module
10-bit IC Type AD7533 with mechanical switches
MIcroprocessor interfaced 10-bit converter
>> Experiments:-
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.
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.
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.
>> Features and Specifications:-
Advanced Experiments-arbitrary waveform generation
Panel Meter for all measurements
A measuring CRO is needed for viewing the waves forms
The experiment is complete in all respect, except a CRO.
