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

  • RE: AD5737是否有替代产品

    AD5757和AD5755也不推荐使用了。

  • 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,

  • AD5757 DAC hardware and software reset

    Hi

    Could you helps to check whether hardware reset and software has the same result for AD5757 chip.

    What is the different of them.

    In my testing, bot hardware and software reset can work well.

    Also, in datasheet, it say that " when power up, make a…
