LM74CIM-3 Description

Short technical summary and product information.

The LM74CIM-3 from Texas Instruments is a digital temperature sensor featuring a Delta-Sigma analog-to-digital converter with an SPI and MICROWIRE compatible interface. It offers a wide operating temperature range of -55°C to 150°C and provides a temperature resolution of 0.0625°C (12-bit plus sign).

 

Key electrical specifications include a supply voltage range of 3.0V to 5.5V. The sensor consumes a typical operating current of 265μA and a shutdown current of 3μA, making it suitable for low-power applications. Temperature accuracy is ±1.25°C (max) within the -10°C to 65°C range.

 

This device is available in an 8-SOIC surface mount package. Its features include a shutdown mode to conserve power between readings and a simple SPI interface, making it ideal for thermal management and protection applications in various electronic systems, such as hard disk drives.
