SPI/MICROWIRE 12-Bit Plus Sign Temperature Sensor
LM74
SPI/MICROWIRE™ 12-Bit Plus Sign Temperature Sensor
General Description

The LM74isa temperature sensor, Delta-Sigma analog-to-
digital converter withan SPI and MICROWIRE compatible
interface. The host can query the LM74at any timeto read
temperature.A shutdown mode decreases power consump-
tionto less than10 µA.This modeis usefulin systems where
low average power consumptionis critical.
The LM74 has 12-bit plus sign temperature resolution
(0.0625˚C per LSB) while operating overa temperature
rangeof −55˚Cto +150˚C.
The LM74’s 3.0Vto 5.5V supply voltage range, low supply
current and simple SPI interface makeit idealfora wide
rangeof applications. These include thermal management
and protection applicationsin hard disk drives, printers, elec-
tronic test equipment, and office electronics. The LM74is
availablein the SO-8 packageas wellasan 5-Bump micro
SMD package.
Applications
System Thermal Management Personal Computers Disk Drives Office Electronics Electronic Test Equipment
Features
0.0625˚C temperature resolution. Shutdown mode conserves power between temperature
