GENERAL DESCRIPTION
The TMP35/TMP36/TMP37 are low voltage, precision centi-
grade temperature sensors. They provide a voltage output that
is linearly proportional to the Celsius (centigrade) temperature.
The TMP35/TMP36/TMP37 do not require any external
calibration to provide typical accuracies of ±1°C at +25°C
and ±2°C over the −40°C to +125°C temperature range.
The low output impedance of the TMP35/TMP36/TMP37 and
its linear output and precise calibration simplify interfacing to
temperature control circuitry and ADCs. All three devices are
intended for single-supply operation from 2.7 V to 5.5 V maxi-
mum. The supply current runs well below 50 µA, providing
very low self-heating—less than 0.1°C in still air. In addition, a
shutdown function is provided to cut the supply current to less
than 0.5 µA.
The TMP35 is functionally compatible with the LM35/LM45
and provides a 250 mV output at 25°C. The TMP35 reads
temperatures from 10°C to 125°C. The TMP36 is specified from
−40°C to +125°C, provides a 750 mV output at 25°C, and
operates to 125°C from a single 2.7 V supply. The TMP36 is
functionally compatible with the LM50. Both the TMP35 and
TMP36 have an output scale factor of 10 mV/°C.

The TMP37 is intended for applications over the range of 5°C
to 100°C and provides an output scale factor of 20 mV/°C. The
TMP37 provides a 500 mV output at 25°C. Operation extends
to 150°C with reduced accuracy for all devices when operating
from a 5 V supply.
The TMP35/TMP36/TMP37 are available in low cost 3-lead
TO-92, 8-lead SOIC_N, and 5-lead SOT-23 surface-mount
packages.

1 Digital inputs are protected; however, permanent damage can occur on
unprotected units from high energy electrostatic fields. Keep units in
conductive foam or packaging at all times until ready to use. Use proper
antistatic handling procedures.
2 Remove power before inserting or removing units from their sockets.
Data Sheet
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device in
socket.
