Texas Instruments recommends a 4-layer PCB with a solid ground plane and a thermal relief pattern around the device to minimize thermal gradients and ensure accurate temperature readings.
The open-drain output of the LM62CIM3 requires an external pull-up resistor to VCC. The value of the resistor depends on the specific application, but a typical value is 1 kΩ to 10 kΩ.
The maximum cable length for the LM62CIM3's digital output depends on the specific application and the noise environment. However, as a general guideline, Texas Instruments recommends keeping the cable length below 10 inches (25 cm) to minimize signal degradation.
The LM62CIM3 does not require calibration for typical applications. However, for high-accuracy measurements, users can perform a one-point calibration by measuring the device's output at a known temperature point and adjusting the offset accordingly.
The LM62CIM3's response time to temperature changes is typically around 10 seconds to 30 seconds, depending on the thermal mass of the device and the surrounding environment.
