- ±2 °C Accuracy Over Temperature (typ)
- ±0.5 °C Linearity (typ)
- Stable with Large Capacitive Loads
- Specified -40 °C to +125 °C, Operation to +150 °C

- Shutdown Current 0.5 µA max
The TMP35 / TMP36 / TMP37 are low voltage, precision centigrade 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 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 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.

ADALM-SR1
Switching Regulator Active Learning Module
Product Detail
The ADALM-SR1 (Analog Devices Active Learning Module, Switching Regulator) board is a companion module for several switching regulator exercises covering buck and boost regulators:
- Boost and Buck converter elements and open-loop operation
- Buck Converters: closed loop operation
- Boost Converters: closed loop operation
The circuits required for these exercises exceed the complexity that can be constructed on a breadboard, so the ADALM-SR1 was designed as a flexible platform for experimenting with power electronics. Onboard current sense amplifiers, adjustable electronic load, and feedback signal injection circuitry eliminate the need for expensive equipment — the only additional equipment required is:
- 5V USB wall adapter
- Basic adjustable power supply for input power (0-12V, 2A)
- Multimeter
- ADALM2000 or basic oscilloscope (2 channels with trigger, >10MHz bandwidth)
