  Isolated Data Transmission and Power Conversion
  Integrated Into a Surface Mount Package
  Keith Bennett Galvanic isolation is used in a variety of industries, most commonly to provide safety
  against potentially lethal voltages. Isolation is also used to eliminate the effects of noise
  and common mode voltage differences created by ground loops, or as a level shifter
  between dissimilar operating voltages. Typically, building an isolated system requires
  a number of passive and active components on either side of the isolation barrier, in
  addition to the barrier components themselves. These barrier components can be
  optical, magnetic, capacitive, RF or even GMR (giant magnetoresistance) devices.
  Barrier components are notoriously difficult to use, adding significant design
  time and cost to isolated systems. With
  this in mind, Linear Technology has
  developed a line of ВµModuleВ® isolators that reduces the design of isolated
  systems to simply plugging in a module—no complex barrier components
  are required. In fact, ВµModule isolators
  require no external components at all.
  Linear Technology ВµModule isolators
  use magnetically coupled techniques to
  provide data and power isolation in a
  single package. The result is an easy-touse, low power, robust solution with
  excellent field immunity. The LTM2881
  isolated RS485/RS422 transceiver and LTM2882 dual isolated RS232 transceivers use ВµModule isolator technology
  to provide complete transceiver-pluspower solutions in 15mm Г— 11.25mm …
