ADL5304 current detection range？

Hi there,

It depends on the part, and temperature. Down at the low end of input current range, there will be more temperature variation:

If mass production application, see also datasheet Figures 11 and 13, and compare that against your accuracy requirement.

Hi Bruce：

When VNEG is -5V,  the mark trace is GND or not？the PCB layout show as fig2 is ok or not?

Thank you!

fig2:

Hi there,

In Figure 1, the arrows point to copper that connects to the VSMx pins.

In Figure 2, we recommend a defined guard ring around the INUM node connections. Ref. datasheet page 26.

Hi Bruce: when use nea

Hi Bruce:

when use negative power, VSMx are connect to GND, so the Guard ring of INUM is GND or not？

Do you have the layout guide of Guard ring, like the Schematic diagram?

You're correct. When VSMx= Gnd, the guard ring can also be Ground.
