ADS54J60: Offset binary output setting

JH Shin

Part Number: ADS54J60

Hello,

Besides the two registers below, are there any additional registers a user needs to control for setting the offset binary of the ADS54J60?

My customer has controlled the two registers, but they don't get the offset binary output.

Thank you.

JH

    Hi JH, 

    Thank you for your patience. I set this part up in the lab and saw the same behavior as you describe using the board I was testing. 

    You are doing the correct register writes. (Register 0x43 -> 0x01; Register 0x4B -> 0x20)

    The trick is that one additional "pulse reset" must be done to address 0x680000. Toggle the reset [bit 0] from a 1 to a 0. I confirmed that this gave me the two's complement output on my board. Let us know if you run into any issues getting it to work. 

    Regards, Amy
