LM74 SPI/Microwire12-Bit Plus Sign Temperature Sensor

Check for Samples: LM74

FEATURES

DESCRIPTION

The LM74 is a temperature sensor, Delta-Sigma

analog-to-digital 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.

5-Bump DSBGA Package Saves Space

APPLICATIONS

The LM74 has 12-bit plus sign temperature resolution

(0.0625°C per LSB) while operating over

Disk Drives

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

SOIC package as well as the 5-Bump DSBGA

package.
