  • What is the difference between the AD5755, AD5757, and AD5755-1

    What is the difference between the AD5755, AD5757, and AD5755-1?

  • RE: AD5737是否有替代产品

    可以使用AD5757 或者 AD5755

  • AD5757 & AD5755

    Hi,

    1- I do not want to use Dynamic Power Control in AD5757 and AD5755. Can I connect my 12 volt to Vboost or only min voltage is 15 volt.

    2- In AD5755 can I do not connect AVss to -volt And the Vout_x is only 0-5 or 0-10 volt.

    Regards,

     

  • RE: Ad5757 from eval board doesn't answer

    Hi msamera,

    SDO from AD5757 (J11) is connected to MISO pin on master board.

  • RE: AD5757在使用中的功耗大问题？

    "输出端开路时二次电流大" 表示什么意思呢，最好贴一下电路， AD5757的输出电流为4-20mA

    AD5757 内部有动态电源，可以根据负载调整输出电压，进而调整功耗

  • RE: 这样使用AD5757和AD5754的用法是否正确

    AD5757基本正确。

    AD5754不需要在输出端链接2Kohm的电阻和4nF的电容.

  • RE: AD5755 with external MOS transistor

    Hi Harvey,

    Thanks for your feedback. The transistor should be a PMOS.

    The AD5757 board had used a NTLJS4149PTAG but this is now obsolete. We plan to use the FDMA530Z in future boards instead.

    Kind Regards,

    David
