Texas Instruments TMP113 I2C-Compatible Digital Temperature Sensor
Texas Instruments TMP113 I2C-Compatible Digital Temperature Sensor offers an accuracy of ±0.3°C across the -25°C to 85°C temperature range with an on-chip 12-bit analog-to-digital converter (ADC) that provides a temperature resolution of 0.0625°C. This device comes in a compact 6-pin WCSP package.
The TMP113 is designed to operate from a supply range as low as 1.4V, with a low average and shutdown current of 1.4µA (at 1Hz) and 70nA, allowing for an on-demand temperature conversion and maximizing battery life. At the same time, the supply can be raised to as high as 5.5V for a range of industrial applications with only 2m°C/V DC power supply rejection. This device has a very fast thermal step response equal to 0.2s with a flexible PCB.
The Texas Instruments TMP113 production units are 100% tested against NIST-traceable sensors and verified with NIST-traceable equipment through ISO/IEC 17025 accredited calibrations.
