DESCRIPTION
The TMP20 is a CMOS, precision analog output
temperature sensor available in the tiny SOT563
package. The TMP20 operates from –55°C to +130°C
on a supply voltage of 2.7V to 5.5V with a supply
current of 4μA. Operation as low as 1.8V is possible
for temperatures between +15°C and +130°C. The
linear transfer function has a slope of –11.77mV/°C
(typ) and has an output voltage of 1.8639V (typ) at
0°C. The TMP20 has a ±2.5°C accuracy across the
entire specified temperature range of –55°C to
+130°C.
The TMP20 4μA (max) supply current limits
self-heating of the device to less than 0.01°C. When
V+ is less than 0.5V, the device is in shutdown mode
and consumes less than 20nA (typ).
The TMP20 is available in either a 5-lead SC70 or
6-lead SOT563 package, reducing the overall board
space required.

Note:
NC or no-connect pin must be grounded or left floating. Pin 2 on the DRL package has no internal connection; pin 2
on the DCK package is connected to the die substrate. See Layout Information for more information about optimizing
the connection of pin 2 on the DCK package for thermal and electrical performance.
