Temperature Measurement Using Data Acquisition Systems
Design Note 5
William Rempfer and Guy Hoover
Introduction
Accurate temperature measurement is a difп¬Ѓcult 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 ampliп¬Ѓers 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 speciп¬Ѓed 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
40ОјA supply current per ampliп¬Ѓer, the LT1178/LT1179 dual and quad with 13ОјA per ampliп¬Ѓer. The LT1006/
LT1013/LT1014 single, dual and quad have faster speed …
