The recommended layout and routing for the DS1721S+T&R involves keeping the device away from high-current carrying traces, using a solid ground plane, and minimizing the length of the traces connecting the device to the microcontroller. Additionally, using a 4-layer PCB with a dedicated ground plane and placing the device on the top layer can help reduce noise and ensure accurate temperature readings.
The DS1721S+T&R does not require calibration for typical temperature measurement applications. However, for high-accuracy applications, calibration can be performed by comparing the device's temperature readings with a calibrated thermometer and adjusting the device's internal calibration registers accordingly.
The maximum cable length for the 1-Wire interface of the DS1721S+T&R is approximately 100 meters, depending on the cable type and quality. However, it is recommended to keep the cable length as short as possible to minimize signal degradation and ensure reliable communication.
Yes, the DS1721S+T&R is designed to operate in high-vibration and high-shock environments. However, it is recommended to follow proper mounting and packaging guidelines to ensure the device's reliability and accuracy in such environments.
To ensure the DS1721S+T&R is properly powered and reset during power-up, it is recommended to follow the power-up sequence outlined in the datasheet, which includes a minimum power-on reset pulse width of 1.5 ms and a power supply voltage of 3.3 V to 5.5 V.
