TMP124

SBOS272B – JUNE 2003 – REVISED DECEMBER 2003

1.5°C Accurate Programmable

Digital Temperature Sensors

with SPI™ Interface

DESCRIPTION

FEATURES

● DIGITAL OUTPUT: SPI-Compatible Interface

The TMP122 and TMP124 are SPI-compatible temperature

sensors available in SOT23-6 and SO-8 packages. Requir-

ing only a pull-up resistor for complete function, the TMP122

and TMP124 temperature sensors are capable of measuring

temperatures within 2°C of accuracy over a temperature

range of –40°C to +125°C, with operation up to 150°C.

Programmable resolution, programmable set points and shut

down function provide versatility for any application. Low

supply current and a supply range from 2.7V to 5.5V make

the TMP122 and TMP124 excellent candidates for low-

power applications.

● PROGRAMMABLE RESOLUTION:

9- to 12-Bits + Sign

● ACCURACY:

±1.5°C from –25°C to +85°C (max)

±2.0°C from –40°C to +125°C (max)

● LOW QUIESCENT CURRENT: 50µA

● WIDE SUPPLY RANGE: 2.7V to 5.5V

● TINY SOT23-6 AND SO-8 PACKAGES

● OPERATION TO 150°C

● PROGRAMMABLE HIGH/LOW SETPOINTS

The TMP122 and TMP124 are ideal for extended thermal

measurement in a variety of communication, computer, con-

sumer, environmental, industrial, and instrumentation appli-

cations.

APPLICATIONS

● POWER-SUPPLY TEMPERATURE MONITORING

● COMPUTER PERIPHERAL THERMAL PROTECTION

● NOTEBOOK COMPUTERS

● CELL PHONES

● BATTERY MANAGEMENT

● OFFICE MACHINES

● THERMOSTAT CONTROLS

● ENVIRONMENTAL MONITORING and HVAC
