LOW-VOLTAGE SOT-23 TEMPERATURE SENSOR
PRODUCT SPECIFICATION
Pin Configuration
New Release Specification
General Description
The aTS50 is a high-precision CMOS temperature
sensor that provides a cost-effective solution for
applications requiring high-accuracy low-power
temperature monitoring. The aTS50 output voltage
ramp is extremely linear and has a slope of 10mV/°C.
With a supply voltage of 2.7V to 6V, the aTS50 is
accurate to ±1°C over a temperature range of −40°C to
125°C and has a typical room temperature accuracy of
±0.5°C. Reducing the supply voltage to 2.7V does not
change the negative and positive temperature
extremes. As well, the aTS50 does not require
external calibration. Calibration of each device is
performed at the factory.

1. Absolute maximum ratings are limits beyond
which operation may cause permanent damage to
the device. These are stress ratings only;
functional operation at or above these limits is not
implied.
2. Human Body Model: 100pF capacitor discharged
through a 1.5kΩ resistor into each pin. Machine

Notes:
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.
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.
7. Max Self Heating = θJA x (VDD x IDD). Assumes a capacitive load.

Mounting
The aTS50 can be easily mounted by gluing or
cementing it to a surface. In this case, its temperature
will be within about 0.2°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
aTS50 die will be at an intermediate temperature
between the surface temperature and the air
temperature.
temperature is being measured. These printed circuit
board lands and traces will not cause the aTS50’s
temperature to deviate from the desired temperature.
Alternatively, the aTS50 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 aTS50 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 aTS50 or its connections.
To ensure good thermal conductivity, the backside of
the aTS50 die is directly attached to the GND pin. The
lands and traces to the aTS50 will, of course, be part of
the printed circuit board, which is the object whose

Data Sheet Classifications
Preliminary Specification
This classification is shown on the heading of each page of a specification for products that are either under
development(design and qualification), or in the formative planning stages. Andigilog reserves the right to
change or discontinue these products without notice.
New Release Specification
This classification is shown on the heading of the first page only of a specification for products that are either
under the later stages of development(characterization and qualification), or in the early weeks of release
to production. Andigilog reserves the right to change the specification and information for these products
without notice.
Fully Released Specification
Fully released datasheets do not contain any classification in the first page header. These documents contain
specification on products that are in full production. Andigilog will not change any guaranteed limits without
written notice to the customers. Obsolete datasheets that were written prior to January 1, 2001 without
any header classification information should be considered as obsolete and non-active specifications, or in
the best case as Preliminary Specifications.
