The recommended layout and routing for the DS4312D+ involves keeping the analog and digital grounds separate, using a solid ground plane, and minimizing the length of the traces between the device and the power supply. Additionally, it is recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure the accuracy of the temperature measurement, it is recommended to calibrate the device, use a high-accuracy voltage reference, and minimize the thermal gradient across the device. Additionally, the device should be operated within its specified temperature range and the temperature sensor should be placed in close proximity to the device being measured.
The maximum allowed voltage on the VCC pin is 5.5V. Exceeding this voltage can cause permanent damage to the device.
The power-up sequence for the DS4312D+ involves applying the power supply voltage (VCC) before applying the input voltage (VIN). This ensures that the internal voltage regulator is enabled before the input voltage is applied.
The recommended input capacitor value for the VIN pin is 10uF to 22uF. This value helps to filter out noise and ripple on the input voltage.
