LTC1966CMS8#PBF

The LTC1966CMS8#PBF is a true RMS-to-DC Converter that utilizes an innovative patented ?? 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 1V peak and offers unprecedented linearity. Unlike previously available RMS-to-DC converters, the superior linearity of the converter allows hassle free system calibration at any input voltage. It also has a rail-to-rail output with a separate output reference pin providing flexible level shifting. This operates on a single power supply from 2.7 to 5.5V or dual supplies up to ±5.5V. A low power shutdown mode reduces supply current to 0.5µA.
