Product Overview

The LM73CIMK-1/NOPB is an integrated, digital-output Temperature Sensor featuring an incremental Delta-Sigma ADC with a two-wire interface that is compatible with the SMBus and I 2C interfaces. The host can query the device at any time to read temperature. The user can optimize between the conversion time and the sensitivity of the LM73 by programming it to report temperature in any of four different resolutions. Defaulting to 11-bit mode (0.25°C/LSB), the LM73 measures temperature in a maximum time of 14ms, making it ideal for applications that require temperature data very soon after power-up. In its maximum resolution, 14-bit mode (0.03125°C/LSB), the LM73 is optimized to sense very small changes in temperature. A single multi-level address line selects one of three unique device addresses.
  • Supports 400KHz Operation
  • Shutdown mode with one-shot feature available for very low average power consumption
  • Programmable digital temperature resolution from 11-bit to 14-bit
  • Fast conversion rate ideal for quick power up and measuring rapidly changing temperature
  • Open-drain ALERT\ output pin goes active when temperature is above programmed temperature limit
  • Very stable, low-noise digital output
  • 0.25 to 0.03125°C Resolution
  • 3 Selectable addresses per version for a total of 6 possible addresses
  • Green product and no Sb/Br
