• ADA4853 DISABLE Pin

    Can this pin be left floating with the result that the amplifier is in an enabled state?

  • ADA4853/ADA4430 "disable" pin

    Hey,

     We have both ADA4853-1 and ADA4430-1 on our board.

    in some scenario it can get a 3.3V in the "disable" pin while no voltage applied to the supply (Vs).There are no details in the datasheet (in the A.M.R section ) referes to this case.

  • ADE7880 - 3 phase 3 wire delta configuration

    Hi,

    As per the ADE7880 datasheet pg. 43, in three phase three wire delta configuration, Phase B active, reactive and apparent powers are 0.

    So, I would like to know if there is a way to find out the Phase B power data in three wire delta configuration…

  • 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,

  • 3-phase system measurement and 3 single-phase system measurement by ADE9000, ADE9078

    Hello,

    Can we measure a 3 phase system and a 3 single-phase by same circuit using ADE9000 or ADE9078? Off course the meassurement points of the 3 phase system and the 3 single-phase system are different. If no, could you please advise me the connection in…

  • ltc6957-3 : always 3.3V at the output

    We are trying to double a clock frequency with the circuit below.

    The problem of the circuit is when we put a signal from an SMA (adapted 50 Ohms) the output of my LTC6957-3 stayed
