Frequently Asked Questions
What is the accuracy and resolution of the TMP275AIDGKT?
The TMP275AIDGKT offers ±0.5°C maximum accuracy over the -25°C to +85°C range and ±2°C over the full -40°C to +125°C range. It features 12-bit resolution, providing a temperature step of 0.0625°C, making it suitable for precise thermal monitoring applications.
Is the TMP275AIDGKT compatible with the LM75 temperature sensor?
Yes, the TMP275AIDGKT is designed to be pin-compatible and register-compatible with the industry-standard LM75, allowing it to be used as a direct drop-in replacement. It shares the same I2C/SMBus interface and 8-pin MSOP package footprint, simplifying upgrades to higher accuracy designs.
What interface does the TMP275AIDGKT use and how many devices can be connected?
The TMP275AIDGKT communicates via a 2-wire I2C/SMBus interface. Up to eight devices can be connected on the same bus simultaneously by configuring the three address pins (A0, A1, A2), making it ideal for multi-zone temperature monitoring systems.
What package type is the TMP275AIDGKT and what are its dimensions?
The TMP275AIDGKT comes in a VSSOP-8 (MSOP-8) surface-mount package with a body size of 3 mm × 3 mm and a height of 1.1 mm. This compact footprint is well-suited for space-constrained designs in industrial and consumer electronics.
