8.3 Best Design Practices

Do not leave the inputs of the AMC1306M25E unconnected (floating) when the device is powered up. If the device inputs are left floating, the input bias current can drive the inputs to a positive value that exceeds the operating common-mode input voltage and DOUT is permanently high, as described in the Output Behavior in Case of Input Common-Mode Overrange section.

Connect the high-side ground (AGND) to INN, either by a hard short or through a resistive path. A DC current path between INN and AGND is required to define the input common-mode voltage. Take care not to exceed the input common-mode range as specified in the Recommended Operating Conditions table. For best accuracy, route the ground connection as a separate trace that connects directly to the shunt resistor rather than shorting AGND to INN directly at the input to the device. See the Layout section for more details.
