Texas Instruments TMP110 I2C-Compatible Digital Temperature Sensors
Texas Instruments TMP110 I2C-Compatible Digital Temperature Sensors come in an ultra-small (0.64mm2) 5-pin package. The small size and height of the package optimize volume-constrained systems, which DSBGA packages can be considered unsuitable. Unlike DSBGA packages of comparable size, the TMP110 provides a 5th pin that can be used as an address or alert pin. This feature provides flexibility for scalability of the number of sensors or monitoring critical thermal events.
The Texas Instruments TMP110 offers an accuracy of ±1.0°C across the temperature range. Its on-chip 12-bit analog-to-digital converter (ADC) has a temperature resolution of 0.0625°C. The TMP110 is designed to operate from a supply range as low as 1.14V, with a low average and shutdown current of 3.2µA (at 1Hz) and 0.15µA, respectively. This feature allows for on-demand temperature conversion and maximizes battery life. The supply can also be raised to as high as 5.5V for various industrial applications.
