Up to 256 devices can be connected to a single 1-Wire bus, but it's recommended to limit it to 10-20 devices for reliable operation.
The DS1822Z+T&R has a built-in voltage regulator and noise filter to ensure reliable operation even with noisy power supplies. However, it's still recommended to use a clean and regulated power supply to ensure accurate temperature readings.
Yes, the DS1822Z+T&R can operate in temperatures ranging from -55°C to +125°C, making it suitable for high-temperature applications. However, the accuracy of the temperature readings may degrade at extreme temperatures.
The DS1822Z+T&R has a built-in parasitic power supply circuit that allows it to harvest power from the 1-Wire bus, eliminating the need for an external power supply. However, the power supply voltage should be within the recommended range of 3.0V to 5.5V.
The typical current consumption of the DS1822Z+T&R is around 1mA, but it can be as low as 10µA in standby mode.
