The TMP275 is a ±0.5°C accurate integrated digital temperature sensor with a 12-bit analog-to-digital converter (ADC) that can operate as low as 2.7-V supply voltage and is pin- and register-compatible with the Texas Instruments LM75, TMP75, TMP75B, and TMP175 devices. This device is available in SOIC-8 and VSSOP-8 packages, and it requires no external components to sense the temperature. The TMP275 is capable of reading temperatures with a maximum resolution of 0.0625°C (12 bits) and as low as 0.5°C (9 bits), which allows the user to maximize efficiency by programming for higher resolution or faster conversion time. The device is specified over a temperature range of –40°C to 125°C.

The TMP275 device features SMBus and two-wire interface compatibility, and allows up to eight devices on the same bus with the SMBus overtemperature alert function. The factory-calibrated temperature accuracy and the noise-immune digital interface make the TMP275 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.
