LM75AIM

TEXAS INSTRUMENTS  LM75AIM  温度传感器芯片, 电压, ± 2°C, -55 °C, +125 °C, SOIC, 8 引脚

The is an industry-standard Digital Temperature Sensor with an integrated sigma-delta analogue-to-digital converter ADC and I²C interface. The LM75A provides 9-bit digital temperature readings with an accuracy of ±2°C from -25 to 100°C and ±3°C over -55 to 125°C. It operates with a single supply from 2.7 to 5.5V. Communication is accomplished over a 2-wire interface which operates up to 400kHz. It has three address pins, allowing up to eight LM75AIM devices to operate on the same 2-wire bus. It has a dedicated over-temperature output OS with programmable limit and hysteresis. This output has programmable fault tolerance, which lets the user to define the number of consecutive error conditions that must occur before OS is activated. The wide temperature and supply range and I²C interface.
