LM73 具有双线接口的 2.7V、SOT-23、11 至 14 位数字温度传感器
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 I 2C® 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 temperature range (-40°C to 150°C) and providing ±1.0°C accuracy from -10°C to 80°C. 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 14 ms, making it ideal for applications that require temperature data very soon after power-up
