Thermal Response Time
The time required for a temperature sensor to settle to a
specified accuracy is a function of the thermal mass of, and the
thermal conductivity between, the sensor and the object being
sensed. Thermal mass is often considered equivalent to
capacitance. Thermal conductivity is commonly specified using
the symbol
Θ
, and can be thought of as thermal resistance. It is
commonly specified in units of degrees per watt of power
transferred across the thermal joint. Thus, the time required for
the TMP03/TMP04 to settle to the desired accuracy is
dependent on the package selected, the thermal contact
established in that particular application, and the equivalent
power of the heat source. In most applications, the settling time
is probably best determined empirically. The TMP03/TMP04
output operates at a nominal frequency of 35 Hz at +25
°
C, so
the minimum settling time resolution is 27 ms.
interface schematic). The TMP04 pulse output provides a
significant advantage in this application because it produces a
linear temperature output while needing only one I/O pin and
without requiring an A/D converter.
