DESCRIPTION
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.
The TMP122 and TMP124 are ideal for extended thermal
measurement in a variety of communication, computer, con-
sumer, environmental, industrial, and instrumentation appli-
cations.
