  • ltc2990

    I'm using a couple LTC2990 parts and just realized I connected the polarity for V3 and V4 back wards. i.e the chip wants to subtract V3 from v4 meaning V3 should be a greater value than V4. In my case V4 is a greater value then v3. When I configure the…

  • equations to convert the register values to current value of LTC2990

    Dear team,

    I am using LTC2990 to measure the current, i got a question:

     

       

     

    while i used the differential mode, got the value of sign =1 ,and D[14:0] = 7FE5,  so the Vdiffer=-27*19.42= -524 uV,

    the R rense Value is 30 mΩ, in my opinion,  the current…
