DS18S20Z/T&R 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 good rule of thumb is to limit the number of devices to 10-20 per bus.
-
To ensure accurate temperature readings, make sure to follow proper wiring and layout practices, use a high-quality 1-Wire bus, and avoid electromagnetic interference (EMI) sources. Also, perform a parasite power supply connection to the DS18S20, and use a strong pull-up resistor (e.g., 4.7kΩ) on the 1-Wire bus.
-
The main difference is the packaging and operating temperature range. The DS18S20Z is a TO-92 package with an operating temperature range of -55°C to +125°C, while the DS18S20T&R is a SOT-23 package with an operating temperature range of -40°C to +85°C. The T&R version is also a tape-and-reel packaged device, suitable for automated assembly.
-
No, the DS18S20 is designed to operate from 3.0V to 5.5V, but it's recommended to use a 3.3V or 3.0V power supply to ensure reliable operation and minimize power consumption. Using a 5V power supply may cause the device to malfunction or reduce its accuracy.
-
The 1-Wire bus reset signal is an active low signal that must be asserted low for at least 480μs to reset the bus. The reset signal can be generated by the master device (e.g., a microcontroller) or by using a dedicated reset generator IC. Make sure to follow the 1-Wire bus protocol and timing requirements to ensure reliable communication.
