Check for Samples: LM74 FEATURES 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 ОјA. This mode is useful in systems
where low average power consumption is critical. 1 2 0.0625В°C Temperature Resolution
