Temperature Sensors - Analog and Digital Output

Temperature measurement and control is an important function for industrial and laboratory applications, and a variety of temperature sensing devices are used to fulfill these needs. When accuracy is important, thermistors are often used due to their excellent temperature resolution. The MCP9801T-M/SN temperature sensor is a low-cost, commonly available thermistor used for these kinds of applications that has a large temperature measurement range of -55°C to +125°C.

MCP9801T-M/SN Overview

The MCP9801T-M/SN temperature sensor is a simple and low-cost solution for creating an accurate, temperature-dependent measurement system. It is a 3- Terminals thermistor with a negative temperature coefficient (NTC) for measuring temperatures up to +125°C. It has a wide temperature range, excellent accuracy and is easy to use due to its small size, low power requirements, and simple two-wire connection.

Application Fields

The MCP9801T-M/SN temperature sensor is well suited for many temperature measurement and control tasks such as thermostatic controls, industrial systems, density measurements, and temperature control in laboratory and production equipment. It is designed to be used with a variety of microcontrollers, single-board computers, and temperature-sensing circuits. It is also ideal for DIY projects, and can be used to build accurate and reliable temperature monitoring systems. Additionally, it is widely used in applications such as automotive, audio/video equipment, environmental monitoring, and medical instrumentation.

Working Principle

The MCP9801T-M/SN is a three-terminal thermistor with a negative temperature coefficient (NTC). It works based on the principle that the resistance of the NTC thermistor decreases when exposed to an increase of temperature. The resistance is then measured to determine the temperature in a circuit. The MCP9801T-M/SN features a 0.5°C accuracy across its entire temperature range, and has a low power consumption of only 0.5 mA. The thermistor is calibrated to generate an analog voltage output proportional to the measured temperature, allowing for easy integration of the MCP9801T-M/SN into a variety of standard temperature sensing systems.

Features

The MCP9801T-M/SN features a 3-terminal NTC thermistor with a negative temperature coefficient for measurement up to +125°C. It has excellent accuracy and sensitivity, with 0.5°C accuracy across the entire temperature range. Its low power consumption of 0.5 mA further enhances its suitability for many applications. The MCP9801T-M/SN also features an integrated analog voltage output circuit, allowing for easy integration into temperature sensing systems, and provides a simple two-wire connection.

Conclusion

The MCP9801T-M/SN is a low-cost and commonly available thermistor for temperature measurement and control applications. It has a large temperature range from -55°C to +125°C, excellent accuracy and sensitivity, and a low power requirement of 0.5 mA. Its integrated analog voltage output circuit allows for easy integration into temperature sensing systems, and it provides a simple two-wire connection. The MCP9801T-M/SN is an ideal solution for many applications, and is well suited for thermostatic controls, industrial systems, density measurements, and temperature control in laboratory and production equipment.
