The TMP17 is a monolithic integrated circuit 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 1 μA/K. Improved design and laser wafer trimming of the
IC’s thin-film resistors allow the TMP17 to achieve absolute
accuracy levels and nonlinearity errors previously unattainable
at a comparable price.
The TMP17 can be employed in applications from –40C to
+105C where conventional temperature sensors (i.e., thermistor,
RTD, thermocouple, diode) are currently being used. Expensive
linearization circuitry, precision voltage references, bridge
components, resistance measuring circuitry, and cold junction
compensation are not required with the TMP17.
The TMP17 is available in a low cost SOIC-8 surface-mount package
that provides an output current proportional to absolute
temperature. For a wide range of supply voltages, the transducer
