Texas Instruments I2C Temperature Sensor | New Product Brief

This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Texas Instruments I2C Temperature Sensor

Texas Instruments’ TMP1075 I2C Temperature Sensors are lower power, higher accuracy replacements for standard LM75 and TMP75 temperature sensors, and they’re pin and software compatible for easy replacement. 

The TMP1075 is accurate to ±1°C over a wide temperature range, and to within ±2°C over its full -55°C to +125°C operating range, with the integrated 12-bit ADC provides 0.0625°C temperature resolution. It operates from a 1.7V to 5.5V supply, with 2.7µA average current and 0.37µA shutdown current.

The device is compatible with 2-wire SMBus and I2C protocols and can coexist in an I3C bus in Mixed Fast Mode. TMP1075 sensors are available in standard SOIC-8 and VSSOP-8 packages, as well as a 2x2 mm DFN with a 79% smaller footprint than the SOIC package.
