8 +VS VOUT 1 7 NC NC 2 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 maximum. 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 …
