The TMP275-Q1 is a ±0.75°C, accurate integrated digital temperature sensor with a 12-bit, analog-to-digital converter (ADC) that can operate on a supply voltage as low as 2.7 V and is pin- and register-compatible with the Texas Instruments LM75, TMP75, TMP75B, and TMP175 devices. The TMP275-Q1 device is available in 8-pin SOIC and VSSOP packages and requires no external components to sense temperature. The device is capable of reading temperatures with a maximum resolution of 0.0625°C (12 bits) and as low as 0.5°C (9 bits), thus allowing the user to maximize efficiency by programming for higher resolution or faster conversion time. The device is specified over the temperature range of –40°C to +125°C.
The TMP275-Q1 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-Q1 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.
