  Temperature Measurement Using Data Acquisition Systems
  Design Note 5
  William Rempfer and Guy Hoover
  Introduction
  Accurate temperature measurement is a difficult and
  very common problem. Whether recording a temperature, regulating a temperature or modifying a process
  to accommodate a temperature, the LTCВ®1090 family
  of data acquisition systems can provide an important
  link in the chain between the blast furnace temperature
  and the microcontroller. Features of the LTC1090 family
  can make temperature measurement easier, cheaper
  and more accurate.
  High DC input resistance and reduced span operation
  allow direct connection to many standard temperature
  sensors. Multiplexer options allow one chip to measure
  up to 8 channels of temperature information. Single
  supply operation, modest power requirements (~5mW)
  and serial interfaces make remote location possible.
  Switching power on and off lowers power consumption (560ОјW) even more for battery applications.
  Finally, because few sensors have accuracies as good as 0.1%, the 10-bit resolution and 0.05% accuracy of
  the LTC1090 family are just right for most temperature
  sensing applications.

  3V Operation of Linear Technology Op Amps -Design Note 56
  George Erdi
  The latest trend in digital electronics is the introduction
  of numerous ICs operating on regulated 3V or 3.3V
  power supplies. This is a logical development to increase
  circuit densities and to reduce power dissipation. In addition, many systems are directly powered by two AA
  cells or 3V lithium batteries. Clearly, analog ICs which
  work on 3V with good dynamic range to complement
  these digital circuits are, and will be, in great demand.
  Many Linear Technology operational amplifiers work
  well on a 3V supply. The purpose of this design note
  is to list these devices and their performance when
  powered by 3V. The op amps can be divided into two
  groups: single and dual supply devices. The single supply
  op amps are optimized for, and fully specified at, a 5V
  positive supply with the negative supply terminal tied
  to ground. Input common mode voltage range goes
  below ground, and the output swings to within a few
  millivolts of ground while sinking current. Members of
  the single supply family are the micropower LTВ®1077/
  LT1078/LT1079 single, dual and quad op amps with
  40μA supply current per amplifier, the LT1178/LT1179 dual and quad with 13μA per amplifier. The LT1006/
  LT1013/LT1014 single, dual and quad have faster speed …
