SNIT001 February 2024 TMP110
Minimizing the footprint of integrated circuits is always important. However, with temperature sensors, reducing the size of the IC has additional benefits such as reducing the thermal mass of the device—thus, improving the thermal response. TMP110 is TI’s first X2SON packaged temperature sensor. Featuring a significantly smaller form factor than the rest of our packaged temperature sensors portfolio, comparable in size to chip-scale devices, this pushes the boundaries for improved response time and saving space of packaged ICs while also allowing to place the temperature sensor closer to the heat source. In addition, the package protects the die inside from external factors (moisture, light, oxidation). The TMP110 is an I2C digital temperature sensor which offers an additional address orderable and different alert orderables with factory-programmed device-address. To put this into perspective, Figure 1 shows where the new X2SON TMP110 fits within TI's portfolio:
The table below shows a comparison on key specs of this device versus others in TI's portfolio.
Device | Maximum Accuracy | Package | Area (mm) | Power Supply Range | Shutdown Iq | Q100 Available |
---|---|---|---|---|---|---|
TMP110 | 1°C | X2SON | 0.8 x 0.8 | 1.14V to 5.5V | 0.15µA | No |
TMP119 | 0.08°C | DSBGA-6 | 1.488 x 0.95 | 1.7V to 5.5V | 0.15µA | No |
TMP112 | 0.5°C | SOT563 X2SON | 1.6 x 1.6 0.8 x 0.8 | 1.4V to 3.6V | 0.5µA 0.15µA | Yes |
TMP108 | 0.75°C | DSBGA-6 | 1.216 x 0.816 | 1.4V to 3.6V | 0.3µA | No |
TMP114 | 0.2°C | PICOSTAR-4 | 0.76 x 0.76 | 1.08V to 1.98V | 0.16µA | No |
TMP103 | 2°C | DSBGA-4 | 1 x 1 | 1.4V to 3.6V | 0.5µA | No |
Figure 2 shows a visual representation as a PCB layout of how the X2SON package compares in size with other common packages.
As seen above, the TMP110 is considerably smaller than the common packaged temperature sensors. As reference, Figure 3 shows the TMP110 compared to chip-scale devices on a PCB layout along with the smallest leaded package.
Table 2 shows a comprehensive overview of TI's portfolio of local temperature sensors in terms of package and performance over multiple interfaces. Table 3 serves as reference to pick the right device according to the end application needs.
