Product Overview

The LTC1968IMS8#PBF is a precision wide bandwidth RMS-to-DC Converter that uses an innovative delta-sigma computational technique. The benefits of the LTC1968 proprietary architecture, when compared to conventional log-antilog RMS-to-DC converter, are higher linearity and accuracy, bandwidth independent of amplitude and improved temperature behaviour. The LTC1968 operates with single-ended or differential input signals and accurately supports crest factors up to 4. Common mode input range is rail-to-rail. Differential input range is 1VPEAK and offers unprecedented linearity. The LTC1968 allows hassle-free system calibration at any input voltage. The LTC1968 has a rail-to-rail output with a separate output reference pin providing flexible level shifting, it operates on a single power supply from 4.5 to 5.5V. A low power shutdown mode reduces supply current to 0.1µA.
