SNIS212C December 2019 – September 2020 TMP64
PRODUCTION DATA
The TMP64 is a positive temperature coefficient (PTC) linear silicon thermistor. The device behaves like a temperature-dependent resistor, and may be configured in a variety of ways to monitor temperature based on the system-level requirements. The TMP64 has a nominal resistance at 25 °C (R25) of 47 kΩ , a maximum operating voltage of 5.5 V (VSns), and maximum supply current of 100 µA (ISns). This device may be used in a variety of applications to monitor temperature close to a heat source with the very small DEC package option compatible with the typical 0402 (inch) footprint. Some of the factors that influence the total measurement error include the ADC resolution (if applicable), the tolerance of the bias current or voltage, the tolerance of the bias resistance in the case of a voltage divider configuration, and the location of the sensor with respect to the heat source.
