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.
