  • ADP1706 Ripple problem

    I am a newbie power supply designer.

    I have 44 mV of ripple (from my switching regulator)  going into my linear regulator at f=1MHz. I have Cin=Cout=4.7uF. The linear regulator is not reducing the ripple. I tried adding small value caps at the output…

  • RE: ADIS惯性传感器选型问题

    您好。ADIS16334,ADIS16364, ADIS16445零偏稳定性、温度校准范围、温漂等也有不同。详细区别请参考产品数据手册。传感器抗磁场干扰能力比较好,使用控制器通过SPI接口和传感器通信就可以使用。您可以参考ADIS16445,ADIS16485.电源可以参考ADP1706/1707/1708

  • RE: Recommended 1.8V regulator for 8 DDS chips


    Hi Prakash BJ,

    The AVDD and DVDD supply pins of the AD9959 draws a maximum of 325mA when all channels are turned on.

    The 800mA maximum output current of the ADM7160 can only supply up to two DDS chips.

    There are higher current output LDOs such as the…

  • RE: ADP7104供电问题

    您好!

    如果参考我们的评估板设计是没有问题的。选用ADP7104是因为ADP7104的原因是噪声比较低。如果带的负载比较多,您可以考虑使用ADP1706,输出电流可以到1A,但是噪声会高一些。

    此外,在射频应用,通常不建议使用DCDC电源芯片直接为射频器件直接供电,一般都会使用LDO。

  • RE: AD9266 digital output level

    Hi Jacques,

    1)
    Thanks for trying the drive strength adjustment. I should have mentioned this earlier; the different fields in Register 0x15 are enabled/disabled by Bit[7] in Register 0x14. For example, the default value of Register 0x14[7:0] = 0x00, which…

  • RE: AD9777: Full-Scale Output Current limit

    Hi Tom

    Many thanks for this.

    After a lot of wire mods, I got the AD9125 eval board working with the tester. I am able to read and write to the device and get a signal on the DAC outputs using the NCO. I tried the Parallel port, but this was unsucessfull…

  • LDO用于数字负载、模拟负载以及射频负载需要关注哪些指标?

    LDO因为独特的性能优势获得广泛的应用,但不同的应用对LDO的关键特性要求一般不一样,这里小编从专家观点文章中整理一些相关内容分享给大家供参考哦:

    LDO用于数字负载:像ADP170和ADP1706这类数字线性稳压器设计用于支持系统的主要数字要求,通常是微处理器内核和系统输入/输出(I/O)电路。用于DSP和微控制器的LDO必须具有较高的效率,并能处理快速变化的大电流。更新的应用要求给数字LDO造成了巨大的压力,因为处理器内核为了节能而经常改变时钟频率。为了响应软件导致的负载变化而发生的时钟频率变化对LDO的负载调整功能提出了严格的要求…

  • ADP2114/2116 output current

    Hi,

    I am trying to consider DC-DC regulator to the power of analog circuit with a high sensitivity. As a result of reading the attached file, I want to consider the ADP2114/2116.


    1. Using single mode, it outputs 4A/6A. For example, by connecting
