The LTC1967CMS8#TRPBF is a true RMS-to-DC converter that uses an innovative delta-sigma computational technique. The benefits of the LTC1967CMS8#TRPBF proprietary architecture when compared to conventional log-antilog RMS-to-DC converters are higher linearity and accuracy, bandwidth independent of amplitude and improved temperature behavior.
The LTC1967CMS8#TRPBF operates with 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. The LTC1967CMS8#TRPBF allows hassle-free system calibration at any input voltage.
The LTC1967CMS8#TRPBF has a rail-to-rail output with a separate output reference pin providing flexible level shifting; it operates on a single power supply from 4.5V to 5.5V. A low power shutdown mode reduces supply current to 0.1µA.
The LTC1967CMS8#TRPBF is packaged in the space-saving MSOP package, which is ideal for portable applications.
