  Dual Micropower Comparator with Integrated 400mV Reference
  Simplifies Monitor and Control Functions – Design Note 321
  Jon Munson
  Introduction
  The LTВ®6700 dual comparator incorporates features to
  reduce part count in space-critical designs, including
  a trimmed on-chip 400mV bandgap derived reference
  and internal hysteresis mechanisms. The LT6700 also
  features low voltage micropower single supply operation (1.4V to 18V, 7ОјA typical) and Over-The-Top В® I/O
  capability to maximize versatility and provide solutions
  especially useful in portable battery-powered applications. The outputs are open collector to permit logical
  wire-AND functionality, and can drive relatively heavy
  loads (up to 40mA) such as relays or LED indicators.
  The LT6700 supports a wide range of design configurations, but still offers a minimum pin count package
  (ThinSOTв„ў, 6-lead). This is made possible by offering
  the LT6700 in three different versions, each with a
  different input configuration. The LT6700-1 provides
  the designer with one inverting and one noninverting
  input, especially useful in window detection functions;
  the LT6700-2 provides two inverting inputs; and the
  LT6700-3 offers two noninverting inputs. The internal
  reference is connected to one of the inputs of each
  comparator section, as shown in Figure 1, and the …

  An Autoranging True RMS Converter – Design Note 339
  Philip Karantzalis and Jim Mahoney
  True RMS voltage detection is most commonly required
  to measure complex amplitude and time varying signals,
  such as machine or engine vibration monitoring and
  complex AC power line load monitoring. Sometimes
  these applications require accurate input signal measurement over an extremely wide dynamic range—even
  more than the 50dB range of the LTC1966. One solution
  is to add an autoranging function to the LTC1966, thus Introduction
  The LTC В®1966 is a true RMS-to-DC converter that uses
  a ∆Σ computational technique to make it dramatically
  simpler to use, significantly more accurate, lower in
  power consumption and more flexible than conventional log-antilog RMS-to-DC converters. The LTC1966
  RMS-to-DC converter has an input signal range from
  5mVRMS to 1.5VRMS (a 50dB dynamic range with a
  single 5V supply rail) and a 3dB bandwidth of 800kHz
  with signal crest factors up to four. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks
