The TMP75B is an integrated digital temperature sensor with a 12-bit analog-to-digital converter (ADC) that can operate at a 1.8-V supply, and is pin and register compatible with the industry-standard LM75 and TMP75. This device is available in SOIC-8 and VSSOP-8 packages, and requires no external components to sense the temperature. The TMP75B is capable of reading temperatures with a resolution of 0.0625°C and is specified over a temperature range of –55°C to +125°C.
The TMP75B features SMBus and two-wire interface compatibility, and allows up to eight devices on the same bus with the SMBus overtemperature alert function. The programmable temperature limits and the ALERT pin allow the sensor to operate as a stand-alone thermostat, or an overtemperature alarm for power throttling or system shutdown.
The factory-calibrated temperature accuracy and the noise-immune digital interface make the TMP75B the preferred solution for temperature compensation of other sensors and electronic components, without the need for additional system-level calibration or elaborate board layout for distributed temperature sensing.
The TMP75B is ideal for thermal management and protection of a variety of consumer, computer, communication, industrial, and environmental applications.
