Introduction

Temperature Sensors - Analog and Digital Output sensors are used to monitor and control temperatures for a variety of applications. The LM235DT is a Temperature Sensor - Analog and Digital Output sensor that has been designed to provide a high-precision output of both analog and digital signals.

Application Field

The LM235DT is a Temperature Sensor - Analog and Digital Output that is suitable for several different types of applications. The LM235DT can be used for temperature monitoring and control in flash memory systems, LED lighting systems, and automotive systems. In addition, the LM235DT can be used for over-temperature protection in consumer products such as air conditioners, heating systems, and refrigerator units.

Working Principle

The LM235DT is a Temperature Sensor - Analog and Digital Output that works using a thermistor. A thermistor is a semiconductor device that has a conductance that varies with temperature. The LM235DT consists of a negative temperature coefficient (NTC) thermistor and a voltage divider circuit with two resistors. When the temperature increases, the thermistor resistance decreases and the output voltage of the voltage divider will also decrease. This decrease in output voltage can be used to provide an analog or digital signal to indicate temperature changes. The LM235DT is designed to operate over a wide temperature range of -40 to +125 degrees Celsius and can be used for precise temperature sensing. The analog output is adjustable over a 0-5 volt range and the digital output is adjustable from 0.5 to 3.5 volts range. This provides excellent accuracy and repeatability of the temperature measurements. The LM235DT is also capable of providing output signals that match the SAE J-190 temperature range used in most ASSPs. This allows the LM235DT to be used in a wide range of automotive applications where precision temperature sensing is required.

Conclusion

The LM235DT is a Temperature Sensor - Analog and Digital Output that has been designed for a wide range of temperature sensing applications. The LM235DT is designed with a thermistor element and a voltage divider circuit to provide both analog and digital output signals for temperature monitoring and control. The LM235DT is capable of providing accurate temperature measurements over a wide temperature range and is suitable for applications such as flash memory systems, LED lighting systems, automotive systems, and consumer products.
