25°C(max) – −25°C to 110°C, ±2.
1°C(max) – −55°C to 125°C, ±3°C(max) DESCRIPTION The LM74 is a temperature sensor, Delta-Sigma analog-to-digital converter with an SPI and MICROWIRE compatible interface.
The host can query the LM74 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 pow...
