LM71
SPI/MICROWIRE
13-Bit Plus Sign Temperature Sensor
General Description
The LM71 is a low-power, high-resolution digital temperature
sensor with an SPI and MICROWIRE compatible interface,
available in the 5-pin SOT23 or the 6-pin LLP (no pull back)
package. The host can query the LM71 at any time to read
temperature. Its low operating current is useful in systems
where low power consumption is critical.
The LM71 has 13-bit plus sign temperature resolution
(0.03125C per LSB) while operating over a temperature
range of 40C to +150C.
The LM71’s 2.65V to 5.5V supply voltage range, fast con-
version rate, low supply current, and simple SPI interface
make it ideal for a wide range of applications.
