LM74A Datasheet 12-Bit Plus Sign Temperature Sensor

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM74A is a temperature sensor, Delta-Sigma analog-todigital converter with an SPI and MICROWIRE compatible interface in die form.

The host can query the LM74A at any time to read temperature.

A shutdown mode decreases power consumption to less than 10 µA.
