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.
