Use Of Op-Amp In Data Converters

Use of Op amp in Data Converters   Introduction       In Nature signals can be analog or digital. Sometimes we need to convert analog signal into digital equivalent and vice versa, the electronics circuits used for such a conversion area called as  data converters .       Due to the many advantages offered by the digital systems, they are widely used in many fields such as instrumentation, computers, communication and control, in many such applications the signals are not available in digital form, most of the physical quantities such as temperature, pressure, displacement, vibrations etc. are available in analog form. These quantities are represented accurately in analog form but it is difficult to process, store or transmit the analog signal because error gets introduced easily, due to noise.       Hence to reduce these errors, it is always better to express these physical quantities in the digital fo...
