LMH1297: VOD and DEM setting by register

Kazuki Kuramochi

Part Number: LMH1297

Hello expert,

I have question regarding configured value of LMH1297's VOD and DEM by register.
I had confirmed about the configurable setting by register regarding VOD and DEM on this thread.

In this thread, I confirmed that VOD and DEM can be configured as following parameter's
VOD="000", "010", "100", "110"
DEM= "000", "010", "111"

But I cannot found any description regarding the correspondence between register setting and configured value as like as follows.

Would you tell me it?

Thank you and best regards,

Hello nassaer-san,

Thank you for your reply.

Your provided data showing VOD setting from 0 to 7 but register is "000", "010", "100", "110".
If we convert this registers to decimal, it will be "0", "2", "4", "6".

Could we apply this converted register value to this chart?
Also, could I apply same way to think for DEM?

By the way, I've heard from you about there isn't intermediate setting except above register setting.
however, your figured out chart seems there is intermediate value.
Would you tell me why there is intermediate setting value on charge even though it cannot be configure?

Best regards,

Hi Kuramochi-San,

1). Yes you can apply these two figures to VOD and DEM. These are typically value.

2). You are correct there is no intermediate value. These graph has connected these discrete values and there is no intermediate value.
