15.1 Printed-circuit board layout considerations
Table 21.
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach higher temperatures during reflow
soldering, see
For further information on temperature profiles, refer to Application Note AN10365
“Surface mount reflow soldering description” .
Care must be taken in Printed-Circuit Board (PCB) layout to minimize noise induced at the
remote temperature sensor inputs, especially in extremely noisy environments, such as a
computer motherboard. Noise induced in the traces running between the device sensor
inputs and the remote diode can cause temperature conversion errors. Typical sensor
signal levels to the SA56004X is a few microvolts. The following guidelines are
recommended:
Package thickness (mm)
< 1.6
1.6 to 2.5
> 2.5
1. Place the SA56004X as close as possible to the remote sensor. It can be from

and address buses, CRTs are avoided.
