LTC®1967 Precision Extended Bandwidth, RMS-to-DC Converter | Part #: LTC1967CMS8#PBF | DEX

LTC®1967 Precision Extended Bandwidth, RMS-to-DC Converter | Part #: LTC1967CMS8#PBF | DEX is a true RMS-to-DC converter that uses an innovative delta-sigma computational technique. The benefits of the LTC1967 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 LTC1967 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 LTC1967 operates with single-ended or differential in-put 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 LTC1967 allows hassle-free system calibration at any input voltage. The LTC1967 is packaged in the space-saving MSOP package, which is ideal for portable applications.
