LM74A 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. This mode is useful in systems where low.
