TMP35 / TMP36 / TMP37 Low-Voltage Temperature Sensors
Analog Devices’ family of temperature sensors is ideal for automotive applications
ADI’s TMP35/TMP36/TMP37 family of precision centigrade temperature sensors are low voltage and provide a voltage output that is linearly proportional to the Celsius (centigrade) temperature.
Typical accuracies of ±1°C at +25°C and ±2°C over the -40°C to +125°C temperature range are achieved without the use of external calibration. The TMP35/TMP36/TMP37 are intended for single-supply operation from 2.7 V to 5.5 V (maximum). They offer low supply current (below 50 μA) and very low self-heating to less than 0.1°C in still air. All three come with a shutdown function to cut the supply current to less than 0.5 µA as needed.
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. The TMP37’s 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.
