SBASA35A June 2020 – October 2020 AMC3330-Q1
PRODUCTION DATA
Do not leave the analog inputs INP and INN of the AMC3330-Q1 unconnected (floating) when the device is powered up on the high-side. If the device input is left floating, the bias current may generate a negative input voltage that exceeds the specified input voltage range and the output of the device is invalid.
Connect the high-side ground (HGND) to INN, either directly 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.
