Up to 256 DS1629 devices can be connected to a single 1-Wire bus, as each device has a unique 64-bit ROM code.
The DS1629 has a built-in power-on reset circuit that ensures the device is in a known state after power-up. The device resets its internal registers and sets the temperature to a default value.
The DS1629 has an accuracy of ±0.5°C from -10°C to +85°C, and ±1°C from -40°C to +125°C. The accuracy can be affected by factors such as thermal gradients, self-heating, and noise.
The DS1629 can be read as often as every 1ms, but it is recommended to read the data at a slower rate (e.g., every 10ms) to allow the device to perform internal conversions and reduce power consumption.
Yes, the DS1629 can be used in a multi-drop configuration, where multiple devices are connected to the same 1-Wire bus. Each device must have a unique address, and the master device must use the correct protocol to communicate with each slave device.
