Product Overview

The LTC1967CMS8#PBF is a precision extended bandwidth 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 behaviour. 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. It 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.

  • 40kHz Bandwidth to 0.1% additional gain error
  • Bandwidth independent of input voltage amplitude
  • No-hassle simplicity
  • True RMS-DC conversion with only one external capacitor
  • Delta sigma conversion technology
  • Low supply current (330µA typical)
  • Ultralow shutdown current (0.1µA)
  • Differential or single ended flexible inputs
  • Rail-to-rail common mode voltage range inputs
  • Up to 1VPEAK differential voltage
  • Rail-to-rail flexible output
  • Separate output reference pin allows level shifting
