DS1820S Frequently Asked Questions (FAQ)
-
Theoretically, up to 256 devices can be connected to a single 1-Wire bus, but in practice, the maximum number is limited by the bus capacitance, wire length, and noise tolerance. A typical limit is around 10-20 devices.
-
In case of multiple devices with the same ROM code, you can use the 'strong pull-up' method to differentiate between them. This involves connecting a stronger pull-up resistor to the DQ pin of one device, allowing it to dominate the bus.
-
The DS1820S can operate from 3.0V to 5.5V, but it's recommended to use a 5V supply for optimal performance. Operating the device outside this range may affect its accuracy and reliability.
-
To ensure accurate temperature readings, make sure to follow proper PCB layout and thermal design guidelines. Keep the device away from heat sources, use a low-thermal-resistance package, and avoid self-heating effects by minimizing current consumption.
-
Yes, the DS1820S can operate in parasitic power mode, where it derives power from the 1-Wire bus. However, this mode has limitations, such as slower conversion rates and reduced accuracy. Consult the datasheet for specific guidelines on parasitic power operation.
