Hi ADI expert,
Since QC engineer is sorting NG components and found that some component status showed different than good one.
When use DMM diode function to measure pin8/RFC, some showed open status, but some showed forward bias with ground or VDD.
I supposed that RFx pin included TVS diode to prevent ESD , thus some NG components was TVS/Gate damaged, I draw a input structure picture like as:
Could you help us check the RFC input structure? Thanks.
