3 Description

The LM95071 is a low-power, high-resolution digital

temperature sensor with an SPI and MICROWIRE

compatible interface, available in the 5-pin SOT-23.

The host can query the LM95071 at any time to read

temperature. Its low operating current is useful in

systems where low power consumption is critical.

The LM95071 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 2.4-V to 5.5-V supply voltage range, fast

conversion rate, low supply current, and simple SPI

interface of the LM95071 make it ideal for a wide

range of applications.
