PRODUCT DESCRIPTION
The TMP35, TMP36, and TMP37 are low voltage, precision
centigrade temperature sensors. They provide a voltage output
that is linearly proportional to the Celsius (Centigrade) tem-
perature. 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 A/D converters. All three
devices are intended for single-supply operation from 2.7 V to
5.5 V maximum. Supply current runs well below 50
μ
A, provid
ing
very low self-heating—less than 0.1
°
C in still air. In
addition, a
shutdown function is provided to cut supply current
to less
than 0.5
μ
A.
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 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 all available in low cost 3-lead
TO-92, SOIC-8, and 5-lead SOT-23 surface-mount packages.
