Hello.

1.regarding tolerance of 20% end to end.

   does the table list of all the resistance in page 15 are reliable?

2. BIT ASSIGNMENT : BIT 7= VOL, BIT 6=SHDN, BIT 5= WIP .

   Does BIT 0,1,2,3,4,5 are register address?

thanks Kobi.

  • Hi Kobi,

    1. The total resistance can vary ±20%, but the linearity is still ±0.5LSB.  So that values in the table could vary ±20% as well, but they would all vary nearly the same amount.  So for example, in the worst case, all values would be +20% larger, but it is not possible for one value to be +20% and the next to -20%.

    2. The ACR is its own register, with the address of 0x10.  Bits 0-4 are "don't-care" or reserved bits. 

    Thanks,

    Paul

    thanks.

    1. that could be a problem for my design since it base on a static resistance in power up.

    do you have other component that have 1% tolerance in total resistance?

    2. according to your answer, after ACR configuration I need to send another 8 bits of op code.

    Kobi.

    Hi Kobi,

    Could you give a little more detail about your application? Maybe a precision DAC could solve this.

    In regards to the ACR register - this register is just like any other.  It can be read and written to using the same methods as described in section 7.5.2 of the PDS.

    Hi

    the project is accurate dynamic power regulator from 0.6V-5V.

    The Board will have 8 power circuit like that can be adjustable.

    so I need to have stable known resistors that I can change and control via micro controller.

    thanks Kobi.
