3 Description

The TMP110 is a I2C-compatible digital temperature

sensor in an ultra-small (0.64mm2) 5-pin package.

The small size and height package optimizes volume

constrained systems where DSBGA packages can

be considered unsuitable. Unlike DSBGA packages

of comparable size, TMP110 provides a 5th pin that

can either be used as an address pin or alert pin,

providing flexibility for both scalability of number of

sensors or monitoring critical thermal events.

The TMP110 offers an accuracy of ±1.0°C across the

temperature range with an on-chip 12-bit analog-to-

digital converter (ADC) that provides 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, allowing for an on-demand temperature

conversion and maximizing of battery life. The supply

can also be raised to as high as 5.5V for a range of

industrial applications.
