LP2985A: Legacy vs New chip labeling differences

Part Number: LP2985A

Is there a way to tell if a chip is new or legacy from it's packaging? We have 2 chips with different behavior, and are wondering if the extra lines on the chip indicate if it is new or legacy

    Hi Liam,

    The lines above and below the device code are related to the date code for the device. That may not directly indicate whether the chip contains new or legacy silicon, however.

    If you still have the reel or packaging for the two lots, the packaging or reel label will show (20L) CS0: RFB as the manufacturing site for devices with the new chip: 

    Best Regards,
