    From the datasheet:
    "The AGNDSNS pin must be kelvin connected to the AGND pin, with a low-noise, low-impedance path to
    ensure accurate current monitoring. This connection must be made on an internal or bottom layer. It should not segment the thermal tab copper area. This connection serves as the only connection between AGND and
    GND for this device."

    So you do not want any external connection between AGND and GND. It is made internally at the AGNDSNS pin.
