• adp3334's thermal pad

    hi;

    I made a stupid mistake. In one of my project I used a adp3334acp to regulate 7v input power to 6v output. according to the datasheet of adp3334, "the thermal pad is attached to the die substrate, so the thermal planes that the vias attach the package…

  • Problem with ADP3334 at initial startup

    Hello Everyone,

    I have used ADP3334 to execute power sequencing of adas3023. I have connected the SD pin of ADP3334 to FPGA  so that I can turn its output ON at my desired instant. Unfortunately at initial power up When FPGA is loading its program LDO…

  • Wake up problem for your ADP3334

    Dear Sir/Madam,

    I just designed with your ADP3334 LDO power.

    Why ADP3334 bring the output by step up voltage like my attahced scope picture?

    Our product meet the troubble by this step-up power supply.

    I tried to change ADP3334 to new one, but I got…

  • 关于AD7760三路同步采集的主时钟和供电电源问题

    以下问题：（三个AD7760同步采集信号）

    1、AD7760的主时钟输入是用晶振还是FPGA产生的脉冲，（目前，我们用FPGA产生的时钟）

    2、每个AD7760的主时钟共用一个缓冲器（SN7S08）,还是各自用一个缓冲器（SN7S08），（目前，缓冲器同时驱动三个AD7760）

    3、每个AD7760中的VREF是共用ADR434ARZ基准电源，还是各自用ADR434ARZ基准电源，那种方案好。另外，ADR434ARZ基准电源在共用时，是否满足性能要求，如果不满足，是否有相应替代品。（目前，ADR434ARZ基准电源同时提供三个AD7760的基准电压…

  • Why were these selected? (1)

    Q 

    Why were these selected?

     

    A 

    ADP150 delivers 150 mA and very low noise to the PLL & VCO. ADP3334 delivers
    500 mA (required by the modulator) and is sufficient for good modulator
    performance.

  • RE: Interface device for AD7762 (3.3V to 2.5V) and output current in digitals I/O

    True I made a mistake, thank you very much for the info, it is already corrected.

    The EN pin now is connected to VCCY and I use the SD pin (shutdown) to retard 80ms aprox the enable of ADP3334 to ensure VCCA < VCCY during power-up

  • AD7760参考电路图中EMC_FILTER的作用

    在AD7760的参考电路中，“EVAL-AD7760_7762EDZ.pdf”文档中原理图部分的第二页中，LDO ADP3334输出给VDD，中间为什么要接一个EMC_FILTER啊？这个filter的型号是多少啊？以前没接触过，求指导！

  • Voltage Regulator for 16-bit ADC AD7626

    Q 

    We are looking for an appropriate low-noise, low-drop voltage regulator to
    power the 16-bit ADC AD7626. Which device is a better fit : ADP3334 (5V, 2.5V)
    or ADP7104 (5V, 2.5V)? Is there any other voltage regulator that is more
    suitable…

  • ADF4151 eval board

    I bought two ADF4151 eval boards and am in the process of designing a board with the '4151 PLL chip and a proprietary VCO chip on it.  The concern I have is with the USB to SPI interface.  While it's not a big deal to copy the hardware (CY7C68013 USB…
