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.
