Description:
The LM74 is a temperature sensor, Delta-Sigma analog-todigital converter with an SPI and MICROWIRE compatible interface. The host can query the LM74 at any time to read temperature. A shutdown mode decreases power consumption to less than 10 µA. This mode is useful in systems where low average power consumption is critical. 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. 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, electronic test equipment, and office electronics. The LM74 is available in the SO-8 package as well as an 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 reading
● SPI and MICROWIRE Bus interface
● 5-Bump micro SMD package saves space
