3 Description

The TMP20 device is a CMOS, precision analog

output temperature sensor available in the tiny SOT-

563 package. The TMP20 operates from –55°C to

+130°C on a supply voltage of 2.7 V to 5.5 V with a

supply current of 4 µA. Operation as low as 1.8 V is

possible for temperatures between 15°C and 130°C.

The linear transfer function has a slope of –11.77

mV/°C (typical) and an output voltage of 1.8639 V

(typical) at 0°C. The TMP20 has a ±2.5°C accuracy

across the entire specified temperature range of

–55°C to +130°C.

The 4-µA (maximum) supply current of the TMP20

limits self-heating of the device to less than 0.01°C.

When V+ is less than 0.5 V, the device is in

shutdown mode and consumes less than 20 nA

(typical).

The TMP20 is available in a 5-lead SC70 or 6-lead

SOT-563 package that reduces the overall required

board space.
