DESCRIPTION
The LM74A is a temperature sensor, Delta-Sigma analog-to-digital converter with an SPI and MICROWIRE patible 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 average power consumption is critical.
This particular data sheet applies to the LM74 in die form. The LM74 is...
