±2.5°C Low-Power, Analog Out

TEMPERATURE SENSOR

Check for Samples: TMP20

FEATURES

DESCRIPTION

•

±2.5°C ACCURACY FROM –55°C to +130°C

SUPPLY VOLTAGE RANGE: 1.8V to 5.5V

LOW POWER: 4μA (max)

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.

MicroSIZE PACKAGES: SOT563, SC70-5

SC70 PIN-COMPATIBLE WITH LM20

APPLICATIONS

•

CELL PHONES

DESKTOP AND NOTEBOOK COMPUTERS

PORTABLE DEVICES

CONSUMER ELECTRONICS

BATTERY MANAGEMENT

POWER SUPPLIES

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).

HVAC

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.
