The DS75U-C12/T&R should be placed as close as possible to the thermal source, with minimal thermal resistance between the device and the source. A recommended layout is to place the device on a thermal pad or a copper pour, with a minimal number of vias and thermal vias to minimize thermal resistance. Additionally, the device should be placed away from high-current carrying traces and heat-generating components.
The DS75U-C12/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 reading with a known temperature reference point. The device's temperature reading can then be adjusted using the offset register to match the reference temperature.
The maximum cable length for the DS75U-C12/T&R's digital interface depends on the specific application and the signal integrity requirements. As a general guideline, the cable length should be limited to 10 inches (25 cm) to ensure reliable communication. If longer cable lengths are required, signal repeaters or buffers may be necessary to maintain signal integrity.
The DS75U-C12/T&R is designed to operate in a variety of environments, including those with high vibration or shock. However, the device's performance and accuracy may be affected by extreme vibration or shock. It is recommended to follow proper mounting and packaging guidelines to ensure the device's reliability and accuracy in such environments.
The DS75U-C12/T&R has a built-in power-on reset (POR) circuit that ensures the device resets to a known state during power-up. The device also has a brownout detection feature that detects when the supply voltage falls below a certain threshold and resets the device. The POR and brownout detection features help ensure reliable operation and prevent incorrect temperature readings during power-up or power-down sequences.
