3 Description

The LM95071-Q1 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-Q1 at

any time to read temperature. Its low operating

current is useful in systems where low power

consumption is critical.

The LM95071-Q1 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-Q1 make it ideal for a wide

range of applications.
