Product Summary
The LTC1966CMS8 is a true RMS-to-DC converter that utilizes an innovative patented DS computational technique. The internal delta-sigma circuitry of the LTC1966 makes it simpler to use, more accurate, lower power and dramatically more flexible than conventional log-antilog RMS-to-DC converters. The LTC1966CMS8 accepts single ended or differential input signals (for EMI/RFI rejection) and supports crest factors up to 4. The applications of the LTC1966CMS8 include True RMS Digital Multimeters and Panel Meters, True RMS AC + DC Measurements.
