Digital Temperature Sensor with I²C Interface and Alert

• The Digital Temperature Sensor is a fully integrated digital temperature sensor with a 12-bit ADC that can operate at a 1.4V~5.5V supply.

• The Temperature Sensor requires no external components to sense the temperature. The on-chip 12-bit ADC offers resolution down to 0.0625°C.

• Each chip is specially calibrated for ±1°C (max.) accuracy over -55°C to +125°C range in factory before shipment to customers, eliminating the need for users to make any additional adjustments for temperature output.

• The Digital Temperature Sensor with I²C Interface and Alert features SMBus and I²C interface with speed up to 1MHz (2.3MHz at high-speed mode), and allows up to eight devices on the same bus. The programmable temperature limits and the ALT pin allow the sensor to operate as a stand-alone thermostat.

·Power Supply Recommendations：

This temperature sensor has extremely low average power consumption. An RC filter circuit can be added to the power supply pin to further reduce the impact of power supply noise.

·Layout Guidelines：

The device should be placed as far away as possible from noise sources such as high-speed digital buses, coil components, and wireless antennas. The power supply decoupling capacitor should be placed as close as possible to the power and ground pins. A recommended value is 0.1µF. In harsh noise environments, it is recommended to use multiple capacitors of different values ​​in parallel to filter digital noise across multiple frequency ranges.
