I use Arduino to read voltage and current reading using LINX but the readings are varying speedily can can anyone suggest to get smooth sine wave ?

Arduinos are slow and LINX makes then even slower.
You are trying to make a digitizer and the "loop rate" being reported is your actual digital sampling rate.
Take a look at this Acquiring an Analog Signal: Bandwidth, Nyquist Sampling Theorem, and Aliasing
Especially the section on Sample Rate
