The LM73C0QDDCRQ1 is a digital output temperature sensor with an integrated incremental delta-sigma ADC. The LM73-Q1 communicates through a two-wire interface compatible with SMBus and I2C interfaces, and the host can query the LM73-Q1 at any time to read the temperature.

The LM73C0QDDCRQ1 operates over a wide temperature range (–40°C to 125°C) with an accuracy of ±1.45°C from -10°C to 80°C. The LM73-Q1 includes four selectable resolution options that can be used to adjust temperature conversion time and sensitivity for optimal performance. The LM73C0QDDCRQ1 defaults to 11-bit mode (0.25°C/LSB) and can measure temperature up to 14ms, which is ideal for applications that require fast temperature data acquisition after power-up. In the highest resolution 14-bit mode (0.03125°C/LSB), the LM73-Q1 is optimized to sense very small temperature changes.

The LM73C0QDDCRQ1 can select any one of three unique device addresses via a single multilevel address line. An open-drain ALERT output activates when the temperature exceeds a programmable limit. Both data and clock lines are filtered for excellent noise tolerance and reliable communication. In addition, the LM73-Q1 has a time-out feature that automatically resets the clock and data lines if they are held low for an extended period of time. This prevents a bus lock condition without host processor intervention.
