They are used in applications ranging from monitoring HVAC systems in commercial and residential buildings to controlling internal temperature of computers, medical imaging equipment, and induction cooktops. The LM95233CISDX/NOPB is a digital output temperature sensor, which means it is designed to provide a digital temperature reading range over a variety of applications, from automotive systems with 12V inputs down to medical and consumer electronics. This article will discuss the features of the LM95233CISDX/NOPB, its application field, and its working principle.

Useful features of the LM95233CISDX/NOPB include a wide temperature measurement range of -40°C to 150°C, ±2°C accuracy over the entire temperature range, and ±0.5°C accuracy over the main range of -40°C to 105°C. The small package of the IC measures 5mm × 5mm and contains an 8-bit converted temperature data register, a 2-pin CLK/Data Interface, I2C interface, and a wide range of extended features such as freeze alert, hot alert, and overtemperature alarm.

The application field of the LM95233CISDX/NOPB is in any area that requires precision temperature measurement or monitoring, such as in automotive, industrial, or consumer applications. It is suitable for temperature measurement in domestic appliances, including ovens, washing machines, and dishwashers. It is also suitable for medical electronics requiring accurate temperature measurement for monitoring body temperature, in industrial and climatic control systems, and in automotive settings where temperature sensors are used to measure engine coolant temperature.

The working principle of the LM95233CISDX/NOPB is based on an on-board NTC thermistor, which is a temperature-sensing component which changes its resistance with changing temperature. The IC is connected to VREF, GND, and AVCC, while the NTC thermistor is connected to an Analog-to-Digital Converter (ADC) in the IC. The ADC provides the instruction set to the I2C Interface. The microcontroller then reads the temperature by the instruction set which tells it the temperature reading from the temperature sensor.

The LM95233CISDX/NOPB is a digital output temperature sensor, which means it provides an accurate, high- resolution temperature measurement for a wide variety of applications. It offers a wide temperature range, good accuracy, and a small package size. It is suitable for precision temperature measurement in a range of applications, including automotive, industrial, and consumer electronics. Its working principle is based on an on-board NTC thermistor, which is connected to an ADC in the IC. The microcontroller then reads the temperature data that was generated by the ADC.
