3 Description

The TMP63 series of linear thermistors exhibit a large

change in resistance with temperature.

Its

linearity

and

consistent

sensitivity

across

temperature enable simple and accurate methods for

temperature conversion. Low power consumption and

a small thermal mass minimize the impact of self-

heating.

The

built-in

failsafe

behavior

at

high

temperatures and powerful immunity to environmental

variation of these devices is designed for a long

lifetime of high performance. The small size of the

TMP63 series 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 series is currently available in a 0402

footprint-compatible X1SON package.

For complete resistance vs temperature table (R-T

table) computation and helpful methods to derive

temperature, see the Thermistor Design Tool.
