TMP275AIDGKR

The Texas Instruments TMP275AIDGKR is an integrated digital temperature sensor featuring a 12-bit analog-to-digital converter (ADC). It operates over a wide supply voltage range of 2.7 V to 5.5 V and is pin- and register-compatible with devices like the LM75 and TMP75.

This sensor boasts high accuracy, with a maximum deviation of ±0.5°C from -20°C to 100°C, and ±1°C from -40°C to 125°C. It supports user-selectable resolutions from 9 to 12 bits, allowing for optimization between accuracy and conversion speed. The device communicates via SMBus, Two-Wire, and I2C interfaces, supporting up to eight devices on the same bus.

Available in VSSOP-8 and SOIC-8 packages, the TMP275AIDGKR requires no external components for temperature sensing. Its low quiescent current, with a typical value of 50 μA and a standby current of 0.1 μA, makes it suitable for power-sensitive applications. The device is specified for operation across a temperature range of -40°C to 125°C.

Applications for the TMP275AIDGKR include power-supply temperature monitoring, computer peripheral thermal protection, battery management, thermostat controls, and environmental monitoring. Its factory-calibrated accuracy and noise-immune digital interface simplify system design.
