  • ADP3336 configuration

    Hi,

    Please let me know the values of R1 and R2 of ADP3336 configuration (Ref. Data sheet) if the VOUT is 1.2V.

    Thanks and Regards,

  • RE: Noise target for ADAU1701 (AVDD)

    AD's eval board uses not merely a garden variety 3.3V regulator to power the -1701, but a ADP3336 low-noise linear regulator.  Apparently they felt that low power supply noise would show off the -1701 with best advantage.  It will be interesting…

  • RE: ADP2370 empty board order & 2370 buck designer problem

    Sorry, just a follow up question... The linear regulator ADP3336 has quite low voltage drop. So is there any difference in the strength of noise filtering, if I apply say 3.7v on its input, or 5v? Or the noise reduction is independent of the input voltage…

  • ADP7142 for use with ADAU1701

    I need to drop down from a higher voltage than the venerable ADP3336 can handle and so I'm looking at the ADP7142.  It's only rated for 200ma of current though compared to the 800ma for the 3336 but I think that's still enough for the 1701. …

  • RE: Powering up 1701mini board from external supply.

    Thanks for doing this experiment, Bob. I don't have a lot of in-depth knowledge of LDOs, but I know enough to be able to agree with your assessment.

    Skfir, another option if you are really planning on "retiring" the evaluation board would be to lift…

  • RE: 关于ADP2300

    最近做项目,使用单片机的A/D采样,电源是ADP2300接ADP3336转3.3V,如果ADP2300的输出纹波可以很好的控制,就没必要再加个ADP3336了,所以想咨询下开关电源后面加LC滤波器降低纹波方面的文档或资料,

    在AN-1141文档中,

    未看到“当输出端使用两级滤波器时(第一级是LC滤波器,第二级是磁珠加去耦电容)”,相关的计算方法资料,

    可否提供相关资料,因为以后的产品将要做成电池供电的,所以不想使用LDO了,万分感谢。

  • 1/f Noise

    Hello,

    I am very concerned with low frequency noise in Sigma DSP processors. I have tried two different eval boards, the latest one is EVAL 1701. I am measuring 1/f noise that is several microvolts/rtHz (@10 Hz) . I am wondering if you can tell me if…

  • CN0194 - Galvanically Isolated 2-Channel 16-bit ADC

    Hi,

    I am a student in final year of engineering. As a part of our curriculum, we have to make a project. My project is to develop a data acquisition card. The features required for my project is along the lines of CN0194, but instead of SDP board, I…

  • RE: Communication with ADAU 1701

    Here is the schematic of the board.

    The open Pads are connected to a 15-W filter-free stereo class-d audio power amplifier from Texas Instruments (http://focus.ti.com/lit/ds/symlink/tpa3110d2.pdf) with its own surrounding. I don't believe that there…
