LM74A - 12-Bit Plus Sign Temperature Sensor

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.

Key Features

  • n 0.0625˚C temperature resolution. n Shutdown mode conserves power between temperature reading n SPI and.

LM74A SPI/MICROWIRE 12-Bit Plus Sign Temperature Sensor (LM74 in Die Form) November 2004 LM74A SPI/MICROWIRE™ 12-Bit Plus Sign Temperature Sensor (LM74 in Die Form) 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 average power consumption is critical. This particular data sheet applies to the LM74 in die form. The LM74 is available in the SO-8 package as well as an 5-Bump micro SMD package please refer to LM74 data sheet for detailed specifictions pertaining to the packaged parts.
