Temperature Sensors - Analog and Digital Output

The LM335Z is a temperature sensor from TI Precision, a Texas Instruments subsidiary, designed to measure the temperature within a specified temperature range. This temperature range can be from 0 to +100 °C. The temperature range can be extended by using an external required reference resistor. The output of the sensor is linearly proportional to the temperature, with an output of 10 mV/°K at +25 °C and is supplied as a 3-terminal TO-92 package for easy integration in the most commonly used boards.The LM335Z works on the principle of a thermistor, which measures the changes in the electrical resistance of a material in response to the ambient temperature. A thermistor is a semiconductor device made of a semiconductor material which experiences a change in resistance when there is a change in temperature. The lower resistance at higher temperatures is known as the Seebeck effect.The LM335Z operates on the basis of this Seebeck effect, where temperature changes are converted into proportional changes in resistance. When a voltage is applied to the thermistor, a current will be established and the voltage across the device will be linearly dependent on the temperature of the surrounding environment. This enables the LM335Z to be used extensively in temperature monitoring and control applications.The LM335Z can be used to measure temperature in a variety of ways, such as in voltage divider, current divider or bridge networks, depending on the requirement. It can also be combined with other components such as resistors, amplifiers, and transistors to configure more complex circuits which can be used in various applications. For example, the LM335Z can be used in RTD (resistance temperature detector) sensing systems, in thermocouple systems, and to measure thermal expansion of different materials.The LM335Z is ideal for use in temperature sensing and measurement applications where the user requires a low-cost solution with good accuracy. It has stable characteristics over a wide temperature range and provides a linear output for direct thermocouple application with the required reference resistor.Furthermore, it benefits from a low drift and low hysteresis characteristic, a wide linear temperature range and improved accuracy, and a fast response time of only 1 to 2 minutes. Its low power consumption makes it suitable for portable and battery powered applications and the low profile of the integrated circuit allows for efficient board space utilisation.The LM335Z is also equipped with a temperature range extending 10 to 15 °C from the specified range. The output range of any sensor is primarily determined by the supply voltage, the series reference resistor, and the temperature range specified. With the right external components, the commercial temperature range may be extended down to -45 °C and up to +125 °C.Overall, the LM335Z temperature sensor is an ideal choice for applications which require a low-cost, accurate and reliable temperature measurement. It is a convenient tool for obtaining accurate temperature measurement data, and offers the user an easy and effective solution for many common temperature monitoring and control applications.
