aTS45C
Figure 1. aTS45C Output Voltage vs Temperature
Mounting
The aTS45C can be easily mounted by gluing or
cementing it to a surface. In this case, its temperature
will be within about 0.04°C of the temperature of the
surface it is attached to if the ambient air temperature
is almost the same as the surface temperature. If the
air temperature is much higher or lower than the
surface temperature, the actual temperature of the
aTS45C die will be at an intermediate temperature
between the surface temperature and the air
temperature.
To ensure good thermal conductivity, the backside of
the aTS45C die is directly attached to the GND pin.
The lands and traces to the aTS45C will, of course, be
part of the printed circuit board, which is the object
whose
temperature is being measured. These printed circuit
board lands and traces will not cause the aTS45C’s
temperature to deviate from the desired temperature.
Alternatively, the aTS45C can be mounted inside a
sealed-end metal tube, and can then be dipped into a
bath or screwed into a threaded hole in a tank. As
with any IC, the aTS45C and accompanying wiring
and circuits must be kept insulated and dry to avoid
leakage and corrosion. This is especially true if the
circuit may operate at cold temperatures where
condensation can occur. Printed-circuit coatings and
varnishes such as Humiseal and epoxy paint or dips
can be used to ensure that moisture cannot corrode
the aTS45C or its connections.
