General Description
The aTS10 is a high precision silicon integrated circuit
temperature sensor. Improved accuracy relative to it's
industry counterparts the aTS10 maintains an
accuracy of 1C over a temperature range of
-
40C
to 125C. At 25C (room temperature) the accuracy is
calibrated to typically better than 0.5C (V
OUT
=
750mV). This calibration is done during probe and
guaranteed on each device. The aTS10 also maintains
one of the lowest power consumption requirement in
the industry and therefore reduces any inaccuracies
due to self-heating. The device maintains all these
specifications over an operating voltage range of 2.7 to
6 volts.
With the availability within a 5-pin SC-70 package, the
aTS10 has the same functionality as the aTS50 or
aTS51, but in a smaller footprint.

Absolute Maximum Ratings
1
Notes:
1. Absolute maximum ratings are limits beyond
which operation may cause permanent damage
to the device. These are stress ratings only;
functional operations at or above these limits is
not implied.
2. Human Body Model: 100pF capacitor discharged
through a 1.5k
resistor into each pin. Machine
Model: 200pF capacitor discharged directly into
each pin.
3. These specifications are guaranteed only for the
test conditions listed.
4. Accuracy (expressed in C) = Difference
between calculated output voltage and
measured output voltage. Calculated output
voltage = 10mV/C multiplied by device's case
temperature at specified conditions of
temperature, voltage and power supply.

Notes:
5. Non-linearity is defined as the deviation of the output-voltage-versus-temperature curve from the best-fit straight
line, over the device's rated temperature range.
6. Lowest output current should be targeted; higher currents result in more self-heating of the device.

Figure 1. aTS10 Output Voltage vs. Temperature
Mounting
The aTS10 can be easily mounted by gluing or
cementing it to a surface. In this case, its temperature
will be within about 0.02C 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
aTS10 die will be at an intermediate temperature
between the surface temperature and the air
temperature.
To ensure good thermal conductivity, the backside of
the aTS10 die is directly attached to the GND pin. The
lands and traces to the aTS10 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 aTS10's
temperature to deviate from the desired temperature.
Alternatively, the aTS10 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 aTS10 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 aTS10 or its connections.
