LTC1966HMS8 RMS To DC Converter

The LTC®1966 is a true RMS-to-DC converter that utilizes an innovative patented ∆Σ 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 LTC1966 accepts single-ended or differential input signals (for EMI/RFI rejection) and supports crest factors up to 4. Common mode input range is rail-to-rail. Differential input range is 1VPEAK, and offers unprecedented linearity.
Unlike previously available RMS-to-DC converters, the  superior linearity of the LTC1966 allows hassle free system calibration at any input voltage.
The LTC1966 also has a rail-to-rail output with a separate  output reference pin providing flexible level shifting. The LTC1966 operates on a single power supply from 2.7V to 5.5V or dual supplies up to ±5.5V. A low power shutdown mode reduces supply current to 0.5µA.
