  • Behavior of LT1997(-3) in LTSpice

    I am evaluating an LT1997(-3) as a high-side current sense amp in a single-polarity system, up to 100+VDC.

    I modeled it in LTSpice, and am seeing unexpected results.

    The model doesn't seem to work with a single +5V supply, and gain configurations other…

  • LT1997-3 Rn、Rp Calculation

    Hello

    I tried to make a circuit equation like the attached file because I didn't know what to put as Rp, Rn to verify the formula of note 9 in the data sheet.

    Vos,out=(Vos x NOSEGAIN) + Ios x 22.5K + Ib x 22.5K x (1 - Rp/Rn)

    However, the above formula…

  • ADE9078 3相3線Delta接的問題

    最近使用ADE9078的三相電能計量, 遇到以下的問題.

    問題介紹:

    1. 規格書有提到, 計算總功耗(有功, 無功和視在), 須將A相和C相的貢獻相加,

        而我運算的結果, 只有"有功"的算完的數值是正確的, 其餘無功以及視在的數值有落差.

    硬體介紹:

    三相是採用3線Delta, B相接地. 使用EVAL-ADE9078EBZ開發板+EVAL-SDP-CB1Z.

    電流部分使用CT(600:1)

    參數設定:

    VCONSEL設為1, ICONSEL設為0,
