LM73 11-to-14 Bit Digital Temperature Sensor

The LM73 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 I2C ® interfaces. The host can query the LM73 at any time to read temperature. Available in a 6-pin SOT-23 package, the LM73 occupies very little board area while operating over a wide temperatu.

Features

n Single address pin offers choice of three selectable addresses per version for a total of six possible addresses. n SMBus and I2C-compatible two-wire interface n Supports 400 kHz operation n Shutdown mode with one-shot feature available for very low average power consumption n Programmable digital temperature resolution from 11 bits to 14 bits. n Fast conversion rate ideal for quick power up and measuring rapidly changing temperature n Open-drain ALERT output pin goes active when temperature is above a programmed temperature limit n Very stable, low-noise digital ouput. n UL Recognized Compo.
