TMP175AID

The Texas Instruments TMP175AID is a digital temperature sensor designed for accurate temperature monitoring. It features an industry-standard LM75 SOIC-8 footprint and offers I2C and SMBus interface compatibility, allowing up to 27 devices on a single bus. The sensor provides selectable resolutions from 9 to 12 bits, with a maximum accuracy of ±1.5°C (±2°C) across its operating temperature range of -40°C to 125°C. It operates from a wide supply voltage range of 2.7V to 5.5V and consumes low quiescent current, making it suitable for various applications. The TMP175AID includes features like ALERT and one-shot conversion, and supports shutdown and standby modes.

This device is ideal for replacing NTC and PTC thermistors, offering high linearity without the need for calibration or external signal conditioning. Its on-chip 12-bit analog-to-digital converter (ADC) provides resolutions down to 0.0625°C. The TMP175AID is available in an 8-pin SOIC package, suitable for surface mount applications.

Key specifications include an operating temperature range of -40°C to 125°C, a supply voltage range of 2.7V to 5.5V, and a maximum supply current of 85µA. The sensor's accuracy is ±1.5°C typical and ±2°C maximum within the specified operating range. It supports multiple interface protocols, including I2C and SMBus, and offers features like an SMBus Alert function.
