The TMP75AIDGKR from Texas Instruments is a digital temperature sensor in the TMP75 series with an I2C, SMBus, and 2-wire interface in the industry-standard LM75 form factor. Being digital, it reports temperature as a value over the bus rather than an analog voltage, so no external ADC or calibration circuitry is required. The TMP75AIDGKR operates from 2.7V to 5.5V at 410µA nominal supply current, is listed with 1% accuracy, and is rated for -40°C to 125°C. It is supplied in an 8-pin VSSOP measuring 3mm by 3mm with a 970µm thickness, is lead free, halogen free, ELV compliant and RoHS compliant, MSL 2, in tape and reel at 2, 500 per package.

Digital temperature sensors are placed near heat-generating components and airflow paths to feed thermal management: fan speed control, throttling decisions, over-temperature shutdown, and telemetry reported to a system management controller. The LM75 pin and register compatibility is a practical advantage because it lets the part drop into existing designs and reuse existing driver software. Typical deployments include servers and networking equipment, power supplies, industrial controllers, battery packs, and consumer electronics. Buyers are typically computing, networking, industrial, and power systems OEMs and their contract manufacturers.
