Temperature sensors play a key role in ensuring the reliability and safety of an application. LM50BIM3X/NOPB is a temperature sensor that has an analog and digital output. It is composed of a temperature-to-voltage converter and an 8-bit successive approximation ADC (SAR).

General Overview

The LM50BIM3X/NOPB is a high precision integrated temperature sensor that is widely used in many applications. It has an operating temperature range of -40℃ to +125℃, making it ideal for industrial and commercial applications. It has a low sensitivity of 0.5°C (typical) and a maximum offset error of 10°C (maximum). It has a B-grade accuracy (typical) and a wide supply voltage range of 2.8 - 5.5 V.

Application Field

The LM50BIM3X/NOPB is mainly used in applications such as air conditioners, refrigerators, freezers, ovens, washers, dryers, and heaters. It is also used in medical devices, automotive thermostats, and wearables. The device is suitable for use in both commercial and industrial applications as it offers high accuracy and robust performance. It is also used in heat-sensitive applications such as smart phone temperature monitoring and temperature control of battery packs.

Working Principle

The LM50BIM3X/NOPB works by converting the temperature at its sensing junction into a voltage using a temperature-to-voltage converter. This output voltage is then converted by an 8-bit successive approximation ADC (SAR), which gives a digital output which can be used by a processor or microcontroller to control and monitor the temperature of a system. The ADC has a resolution of 0.25°C, while the temperature-to-voltage converter works on a +/-Vref voltage range that is set by the supply voltage or the reference voltage.

Conclusion

The LM50BIM3X/NOPB is a highly accurate temperature sensor with both analog and digital outputs. It is suitable for many industrial and commercial applications and can be used in a wide range of temperature-sensitive applications. The device has a low sensitivity of 0.5°C (typical) and a maximum offset error of 10°C (maximum). It provides reliable and accurate temperature readings for both short and long term applications.
