LM74  
SPI/MICROWIRE 12-Bit Plus Sign Temperature Sensor  
General Description  
The LM74 is a temperature sensor, Delta-Sigma analog-to-  
n Electronic Test Equipment  
Features  
digital converter with an SPI and MICROWIRE compatible  
n 0.0625˚C temperature resolution.  
n Shutdown mode conserves power between temperature  
reading  
interface. The host can query the LM74 at any time to read  
temperature. A shutdown mode decreases power consump-  
tion to less than 10 µA. This mode is useful in systems where  
low average power consumption is critical.  
n SPI and MICROWIRE Bus interface  
n 5-Bump micro SMD package saves space  
The LM74 has 12-bit plus sign temperature resolution  
(0.0625˚C per LSB) while operating over a temperature  
range of −55˚C to +150˚C.  
Key Specifications  
The LM74’s 3.0V to 5.5V supply voltage range, low supply  
current and simple SPI interface make it ideal for a wide  
range of applications. These include thermal management  
and protection applications in hard disk drives, printers, elec-  
tronic test equipment, and office electronics. The LM74 is  
available in the SO-8 package as well as an 5-Bump micro  
SMD package.
