The TMP101NA/3K with Board Mount Temperature Sensors Temp Sensor by Texas Instruments is a highly accurate temperature sensor that is available in a small 800 mil SOIC package. This part is designed for measuring temperatures from -40°C up to +125°C. It features a tSens value of 3K or 3,000 ohms, relative to 25°C, and a common mode range of -0.2V to 4.36V. This part provides accurate temperature readings with an interface compatible with standard single-ended microcontrollers. It is compatible with I2C or SMBus serial interfaces, allowing it to be used in a variety of applications requiring accurate temperature sensing. The TMP101NA/3K also features built-in alarms, allowing it to alert when temperatures exceed a preset limit, and thermal shutdown, which disables the device once a preset temperature has been exceeded. This part is well-suited for a wide range of applications, including environmental monitoring, medical instruments, electronic controls, and other industrial and consumer applications.
