8.2.2 What To Do and What Not To Do

Do not leave the inputs of the AMC3306M05 unconnected (floating) when the device is powered up. If the device inputs are left floating, the input bias current may drive the inputs to a positive value that exceeds the operating common-mode input voltage and the output of the device is undetermined.

Connect the negative input (INN) to the high-side ground (HGND), either by a hard short or through a resistive path. A DC current path between INN and HGND is required to define the input common-mode voltage. Take care not to exceed the input common-mode range as specified in the Section 6.3 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 Section 10 section for more details.

The high-side LDO can source a limited amount of current (IH) to power external circuitry. Take care not to overload the high-side LDO and be aware of derating IH at high temperatures as explained in the Section 7.3.5 section.

The low-side LDO does not output a constant voltage and is not intended for powering any external circuitry. Do not connect any external load to the HLDO_OUT pin.
