The TMP61 is a positive temperature coefficient (PTC) linear silicon thermistor. The device behaves as a temperature-dependent resistor, and can be configured in a variety of ways to monitor temperature based on the system-level requirements. The TMP61 has a nominal resistance at 25°C of 10 kΩ with ±1% maximum tolerance, a maximum operating voltage of 5.5 V, and maximum supply current of 400 µA. The benefits of this device include no extra linearity circuitry, minimized calibration, less resistance toleration variation, larger sensitivity at high temperatures, and simplified conversion methods to save time and memory in the processor. This device can 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 footprint.
