3 Description

The LM71 is a low-power, high-resolution digital

temperature sensor with an SPI and MICROWIRE

compatible interface, available in the 5-pin SOT-23 or

the 6-pin WSON (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

(0.03125°C per LSB) while operating over a

temperature range of ?40°C to +150°C.

The LM71’s 2.65V 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. The LM71Q is available in the 5-lead

SOT-23 package only.
