TI TMP6331QDYARQ1

Linear thermistors offer linearity and consistent sensitivity across temperature to enable simple and accurate methods for temperature conversion. 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 TMP6 series also allows for close placement to heat sources and quick response times. Take advantage of benefits over NTC thermistors such as no extra linearization circuitry, minimized calibration, less resistance tolerance variation, larger sensitivity at high temperatures, and simplified conversion methods to save time and memory in the processor. The TMP63-Q1 is currently available in a 0402 footprint-compatible X1SON package and a 0603 footprint-compatible SOT-5X3 package.
