Introducing the TMP35F Precision Temperature Sensor

The TMP35F is a low voltage, precision centigrade temperature sensor developed by Analog Devices Inc. This product offers a significant advantage in terms of performance and flexibility over conventional temperature sensing solutions. Designed for single-supply operations, it can be powered from as low as 2.7V, making it ideal for battery-powered systems and portable applications.

With its ability to deliver a linear temperature proportional voltage output, the TMP35F eliminates the need for external calibration. The output voltage ranges from 250mV at -40°C to 1250mV at 150°C, providing a scale factor of 10mV/°C. This straightforward interface allows easy interfacing to readout or control circuitry, thus simplifying the overall design process.

The TMP35F does not require any external components for operation, and it is characterized for operation over a wide temperature range of -40°C to 125°C. Its accuracy is ±2°C at room temperature and ±3°C over the full -40°C to 125°C temperature range. This precision, combined with the low self-heating of less than 0.1°C in still air, makes the TMP35F a reliable choice for temperature monitoring in sensitive applications.

Robust and versatile, the TMP35F is well-suited for environmental control systems, thermal protection, industrial process control, and HVAC systems. It can also be employed in applications that require temperature monitoring such as computer thermal management, thermocouple cold junction compensation, or battery management.

Offered in a variety of packages including the 3-lead TO-92 and 8-lead SOIC, the TMP35F provides flexibility in terms of mounting options and space considerations on a PCB. Its low power consumption and shutdown mode make it an energy-efficient component, further enhancing its suitability for power-sensitive designs.

In summary, the TMP35F from Analog Devices Inc. is a top-tier choice for designers seeking a reliable, easy-to-use, and precise temperature sensor. Its integration into any system promises to deliver accurate temperature readings with minimal effort and maximum efficiency.
