The TMP36FSZ is a Low Voltage Temperature Sensor that provides a voltage output that is linearly proportional to the Celsius (centigrade) temperature. It do not require any external calibration to provide typical accuracies of ±1°C at +25°C and ±2°C over the -40 to +125°C temperature range. The low output impedance of the TMP36 and its linear output and precise calibration simplify interfacing to temperature control circuitry and ADCs. This sensor is intended for single-supply operation from 2.7 to 5.5V maximum. The supply current runs well below 50µA, 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 0.5µA. The TMP36 is specified from -40 to +125°C, provides a 750mV output at 25°C and operates to 125°C from a single 2.7V supply. It has an output scale factor of 10mV/°C and functionally compatible with the LM50.

The TMP17 series monolithic Temperature Transducer that provides an output current proportional to absolute temperature. For a wide range of supply voltages the transducer acts as a high impedance temperature dependent current source of 1µA/K. Improved design and laser wafer trimming of the IC’s thin film resistors allows the TMP17 to achieve absolute accuracy levels and nonlinearity errors. A wide operating temperature range (-40 to +105°C) and highly linear output make the TMP17 an ideal substitute for older, more limited sensor technologies (i.e., thermistors, RTDs, diodes, thermocouples). As the TMP17 is a temperature dependent current source, it is immune to voltage noise pickup and IR drops in the signal leads when used remotely. The high output impedance of the TMP17 provides greater than 0.5°C/V rejection of supply voltage drift and ripple.

• Temperature in/current out
• Laser wafer trimming and temperature testing insures that TMP17 units are easily interchangeable
• Electrically rugged
• Temperature resolution of 0.025°C
• 1µA/K High level output
• Excellent repeatability and stability
• Minimal self-heating errors
