LM71 Datasheet (National Semiconductor) - SPI/MICROWIRE 13-Bit Plus Sign Temperature Sensor

LM71, SPI/MICROWIRE 13-Bit Plus Sign Temperature Sensor

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
