Texas Instruments TMP63/TMP63-Q1 Linear Thermistors
Texas Instruments TMP63/TMP63-Q1 Linear Thermistors offer linearity and consistent sensitivity across temperatures to enable simple and accurate methods for temperature conversion. The devices' low power consumption and a small thermal mass minimize the impact of self-heating. With built-in failsafe behavior at high temperatures and powerful immunity to environmental variation, these devices are designed for a long lifetime of high performance. The small size of the Texas Instruments TMP63/TMP63-Q1 also allows for close placement to heat sources and quick response times.
The TMP63/TMP63-Q1 offers benefits over NTC thermistors, such as no extra linearization circuitry, minimized calibration, and less resistance tolerance variation. It also includes a larger sensitivity at high temperatures and simplified conversion methods to save time and memory in the processor. The TMP63/TMP63-Q1 is currently available in a 0402 footprint-compatible X1SON package. The TMP63-Q1 devices are AEC-Q100 qualified for automotive applications.
