The 12-bit resolution gives 0.0625°C per LSB — finer than the ±1°C accuracy, so the digital readout will show more digits than the sensor can guarantee. The extra bits help with trend detection (rate of temperature rise) but not with absolute accuracy. ## Bus interface and addressability Communication is over I²C/SMBus — two wires for clock and data, with the sensor acting as a slave. Multiple TMP175 devices can share the same bus; each has a configurable address via the ADD0 pin, so up to 27 devices can be addressed on one bus without an I²C multiplexer. The I²C interface runs on the same 2.7-5.5 V supply rail — no separate bus voltage translator is needed when the master controller runs at the same voltage. ## Compliance and production status RoHS3 compliant (EU 2015/863), which covers the current restricted substances including the four phthalates. No REACH or UL documentation is carried in the record.","metaTitle":"TMP175AQDRQ1 Texas Instruments Temp Sensor, AEC-Q100","metaDescription":"Texas Instruments TMP175AQDRQ1 digital local temperature sensor, ±1°C accuracy, 2.7-5.5V, -40 to 125°C, 8-SOIC.
