LTC1966CMS8#PBF

LTC1966 is a true RMS-to-DC converter that utilizes an innovative patented ∆Σ computational technique. The internal delta sigma circuitry of the device makes it simpler to use, more accurate, lower power and dramatically more flexible than conventional log antilog RMS-to-DC converters. This device accepts single-ended or differential input signals (for EMI/RFI rejection) and supports crest factors upto 4. Common mode input range is rail-to-rail. Differential input range is 1VPEAK, and offers unprecedented linearity. This device also has a rail-to-rail output with a separate output reference pin providing flexible level shifting. It is widely used in application such as true RMS digital multimeters and panel meters, true RMS AC + DC measurements etc.
