The TMP64 series of linear thermistors exhibit a large change in resistance withtemperature.

Its linearity and consistent sensitivity across temperature enable simple and accuratemethods for temperature conversion. Low power consumption and a small thermal mass minimize theimpact of self-heating. The built-in failsafe behavior at high temperatures and powerful immunityto environmental variation make these devices suitable for a long lifetime of high performance. Thesmall size of the TMP64 series allows for close placement to heat sources and quick responsetimes.

Take advantage of benefits over NTC thermistors such as no extra linearization circuitry,minimized calibration, less resistance tolerance variation, larger sensitivity at hightemperatures, and simplified conversion methods to save time and memory in the processor.

The TMP64 series is currently available in a 0402 footprint-compatible X1SON package.
