  • ADP1720和ADP3300的选择问题

    我需要驱动一个5V，30mA的负载，现在选了两个LDO用来驱动负载，分别是ADP1720和ADP3300，两个都是5V输出，50mA的电流输出，我想问这两个芯片的区别在哪，我的输入也是5V，要求输出纹波小，哪个芯片更符合要求，谢谢|

  • ADP1720：空载输出正常，接负载后电压反而升高

    如题，电路应该是没有问题的，很简单，也排除了电容的问题。

    空载时输出是3.3V，接了ADUCM360的最小系统后，电压升高至4.0V左右。

    不知道是哪里出了问题？

  • CN0300: Maximum Loop Voltage (AIN8 connected to INT_Vref)

    Q 

    CN0300: What is the maximum loop voltage?

     

    A 

    The maximum input voltage that the ADP1720 can handle is 28V. This covers most
    4-20mA networks but some networks supply voltages can be up to 50V.
    CN0300 shows that AIN8 and AIN9 are used to…

  • Error with CN0381

    I think there is a mistake in design CN0381 with the IOV_DD voltage regulator. The ADJ resistor pair for the ADP1720ARMZ-R7 is shows R1=57.6k and R2=27k. If I am reading ADP1720.pdf page 10 correctly, this produces a voltage of 3.8V instead of the desired…

  • Current rating for AD7124-8 - external power supply

    Hello,

    I can't find a current rating for the AD7124-8 evaluation boards, only that the input voltage range is 7-9V. (It looks like the external power source is sent through a linear regulator (ADP1720), but I also couldn't find an input current for this…

  • RE: Bad data and resets when interfacing the AD7124 to Raspberry Pi

    Hi,

    Yes, the AVDD should be 3.3V. The analog part will not power up if AVDD is below the minimum specified level of 2.7V(low and mid power mode) and 2.9V (full power mode). Can you check if all of the jumpers and connections are at all default connections…

  • ADuCM360 AVDD

    Hello

    Our customer is designing his board using ADuCM360.

    He looks that AVDD is connected to outptu of ADP1720 through  some capacitor and a bead in the description of the datasheet P.23 and UG-367 P.174 .

    Do we need some capacitor and a bead  to meet…

  • RE: 关于AD7124-4的问题

    1. ADP1720-ADJ 的输出电压是多少？1.225*(1 + 57.6/27) = 3.838V

    这个问题我之前已经处理，56.7与27 调换一下就可以了。

    2.单片机的IO口做逻辑电平转换，有没有那种IC可以推荐一下给我，5V转3.3V的就可以，

    3.在此谢谢。

  • What is the output voltage when I use 3.3?

    Hi,

    The ADP1720 says that the supply voltage is from 4v to 28v in order to make it work properly.

    My question is that if now I use 3.3v for the input voltage, what will happen? Is the output voltage is 3.3v or something else?

    Thank you.
