LM71

SPI/MICROWIRE™ 13-Bit Plus Sign Temperature Sensor

General Description

The LM71 is a low-power, high-resolution digital temperature

sensor with an SPI and MICROWIRE compatible interface,

available in the 5-pin SOT23 or the 6-pin LLP (no pull back)

package. The host can query the LM71 at any time to read

temperature. Its low operating current is useful in systems

where low power consumption is critical.

The LM71 has 13-bit plus sign temperature resolution

(0.03125˚C per LSB) while operating over a temperature

range of −40˚C to +150˚C.

The LM71’s 2.65V to 5.5V supply voltage range, fast con-

version rate, low supply current, and simple SPI interface

make it ideal for a wide range of applications.
