Temperature sensors for any need
Easy and accurate temperature monitoring and protection
Our temperature sensors accelerate your design process by reducing hardware and software complexity compared to discrete temperature sensors such as NTC thermistor sensors or platinum RTDs (PT100/PT1000) and will help you innovate with high accuracy, low power consumption and small and flexible packaging options. These IC temperature sensors are designed to overcome common design challenges with high accuracy, fast response time and ease-of-use. Visit our applications page to learn more about how temperature sensors supporting standards such as AEC-Q100, NIST and extensive radiation testing are enabling automotive, medical and space applications.
