3 Description

Get started today with the Thermistor Design Tool,

offering complete resistance vs temperature table (RT

table) computation, other helpful methods to derive

temperature and example C-code.

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 TMP64 is currently available in a 0402 footprintcompatible

X1SON package and a 0603 footprintcompatible

SOT-5X3 package.
