LM74 - SPI/Microwire12-Bit Plus Sign Temperature Sensor

General 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.

Key Features

  • 1.
  • 2 0.0625°C Temperature Resolution.
  • Shutdown Mode Conserves Power Between Temperature Reading.
  • SPI and.
