LM70 SPI/MICROWIRE 10-Bit plus Sign Digital Temperature Sensor

Check for Samples: LM70

FEATURES

DESCRIPTION

•

0.25°C Temperature Resolution.

The LM70 is a temperature sensor, Delta-Sigma

analog-to-digital converter with an SPI and

MICROWIRE compatible interface available in WSON

and VSSOP 8-pin packages. The host can query the

LM70 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.

UL Recognized Component

APPLICATIONS

The LM70 has 10-bit plus sign temperature resolution

(0.25°C per LSB) while operating over a temperature

range of −55°C to +150°C.

System Thermal Management

Personal Computers

Disk Drives

The LM70's 2.65V 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.
