ADC12D1620QML-SP: question about pin descriptions

Kazuhiko Hirano

Part Number: ADC12D1620QML-SP

Tool/software:

Hello,

About pin descriptions, there are differences between ADC12D1620QML-SP datasheet and the SMD document as follows. Which is true?

    Hi Hirano-San,

    I can't speak to why the pin names are different but the functionality appears to align between the two docs.  

    1) C2 is the AC-coupling pin.  It can be a common-mode input or GND.  I assume the application for the SMD intends it to be GND.

    2) The reserved pins from the datasheet require a decoupling capacitor

    3) I do not know but they are both grounds for the Track and hold portion of the device

    Regards,

    Geoff

    Hello. Geoff-san,

    Thank you for your reply.

    As per Hirano-san's previous comment, We have confirmed 6 differences in the pin symbols (names) between the datasheet and the SMD. Which document has the correct pin names?

    Also, We would like the incorrect pin names to be the same. Are there any plans to change the document? Please advise me.

    Thanks and Regards,

    koji

    Hirano-San,

    Please defer to the TI datasheet for the correct pin names.  I have informed the appropriate parties about the discrepancy so that it can be corrected.

    Regards,

    Geoff
