LTC1967-精准扩展带宽、RMS至DC转换器
ltc1967描述
the ltc®1967 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 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 ltc1967 allows hassle-free system calibration at any input voltage.
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 is packaged in the space-saving msop package, which is ideal for portable applications.
protected under u.s. patent numbers 6,359,576, 6,362,677 and 6,516,291.
