DESCRIPTION
The LM95071/LM95071-Q1 is a low-power, high-
resolution digital temperature sensor with an SPI and
MICROWIRE compatible interface, available in the 5-
SPI and MICROWIRE Bus Interface
LM95071-Q1 is AEC-Q100 Grade 0 qualified
and is manufactured on an Automotive Grade
flow
pin
SOT-23.
The
host
can
query
the
LM95071/LM95071-Q1 at any time to read
temperature. Its low operating current is useful in
systems where low power consumption is critical.
