SNIS121I – JUNE 1999 – REVISED FEBRUARY 2013
APPLICATION INFORMATION
Mounting
The LM61 can be applied easily in the same way as other integrated-circuit temperature sensors. It can be glued
or cemented to a surface. The temperature that the LM61 is sensing will be within about +0.2°C of the surface
temperature that LM61's leads are attached to.
This presumes that the ambient air temperature is almost the same as the surface temperature; if the air
temperature were much higher or lower than the surface temperature, the actual temperature measured would
be at an intermediate temperature between the surface temperature and the air temperature.
To ensure good thermal conductivity the backside of the LM61 die is directly attached to the GND pin. The lands
and traces to the LM61 will, of course, be part of the printed circuit board, which is the object whose temperature
is being measured.
Alternatively, the LM61 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 LM61 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
paints or dips are often used to ensure that moisture cannot corrode the LM61 or its connections.
The thermal resistance junction to ambient (
θJA) is the parameter used to calculate the rise of a device junction
temperature due to its power dissipation. For the LM61, Equation 1 is used to calculate the rise in the die
temperature.
TJ = TA + θJA [(+VS IQ) + (+VS − VO) IL]
where
IQ is the quiescent current
ILis the load current on the output
(1)
Since the LM61's junction temperature is the actual temperature being measured care should be taken to
minimize the load current that the LM61 is required to drive.
Table 3 summarizes the rise in die temperature of the LM61 without any loading with a 3.3V supply, and the
thermal resistance for different conditions.
