Temperature Sensors - Analog and Digital Output

The LM335D is a type of temperature sensor used in electronic circuits for monitoring the temperature of a system or device. It features a linear output voltage over a wide temperature range that can reliably and accurately report the current temperature. In addition to its robust thermal performance, it also offers low power consumption and is available in both analog and digital output formats.

The LM335D provides a temperature-dependent output voltage that is proportional to the absolute temperature. Its output voltage is designed to be directly proportional to degrees Kelvin (K°), meaning the output voltage increases with increases in temperature. This makes it ideal for use in controlling and monitoring the temperature of many different types of systems. The output voltage is also linearly proportional to temperature, which makes it easy to accurately measure temperatures without any calculation or special software.

The LM335D works by using an internal thermistor, a type of temperature sensitive resistor, to measure the temperature of the environment. The thermistor changes its resistance based on the temperature of the environment, and this resistance is then used to give an output voltage. This output voltage is proportional to the temperature and is measured by the analog or digital output pins.

The LM335D has many potential applications, including:

• HVAC - Building temperature control and monitoring
• Temperature measurement and control of industrial process
• Automotive applications such as HVAC, engine control, and other temperature sensitive components
• Medical devices such as thermometers and temperature sensors
• Consumer temperature sensing applications such as fire alarms, and home appliances.

The LM335D can also be used to measure the temperature of liquids, such as coolants, acids, and other chemical solutions. This makes it ideal for use in scientific experiments or other industrial applications. Its low power consumption and accurate results make it a preferred choice for many industries.

In order to use the LM335D, the power supply and ground connections must be made. The power supply should be between 5V and 15V, and the ground should be connected to a similar ground. The output pin is connected to the input of an ADC (Analog to Digital Converter) or a microcontroller. The output voltage can then be read to give an accurate measurement of the ambient temperature.

The LM335D is based on the famous LM335Z temperature sensor. It has an adjustable output range of 3.0V to 5.5V and an accuracy of ±0.5°C. The LM335D also has a low power consumption of 50uA max, making it ideal for battery-powered applications. It is available in a range of packages and is suitable for both commercial and automotive applications.

The LM335D is a reliable and accurate temperature sensor that is suitable for use in many different applications. It offers a wide temperature range and a linear output voltage that can be used to accurately measure the temperature of a system or device. It is available in analog and digital output formats and requires minimal power consumption, making it an ideal choice for use in many temperature-sensitive applications.
