February 2005
LM95071
SPI/MICROWIRE 13-Bit Plus Sign Temperature Sensor
General Description
The LM95071 is a low-power, high-resolution digital tem-
perature sensor with an SPI and MICROWIRE compatible
interface, available in the 5-pin SOT23. The host can query
the LM95071 at any time to read temperature. Its low oper-
ating current is useful in systems where low power consump-
tion is critical.
The LM95071 has 13-bit plus sign temperature resolution
(0.03125藲C per LSB) while operating over a temperature
range of 鈭?0藲C to +150藲C.
The LM95071鈥檚 2.4V to 5.5V supply voltage range, fast
conversion rate, low supply current, and simple SPI interface
make it ideal for a wide range of applications.
