Overview
The LTC1966CMS8#TR, produced by Analog Devices Inc., is a true RMS-to-DC converter that employs an innovative patented ΔΣ (delta-sigma) computational technique. This converter is designed to be simpler to use, more accurate, lower power, and more flexible compared to conventional log antilog RMS-to-DC converters. It is particularly suited for applications requiring high accuracy and reliability in measuring RMS values of input signals.
