• RE: Dual-supply design from phantom power

    Jerad and I had some off line discussions and the solutions was narrowed to use a 9V battery and generate a regulated +/-9V supply with an additional 3.3V.

     

    For the +/-9V:

    You can use the Coupled SEPIC cuk topology to develop the +/-9V (adjustable…

  • RE: Suggest Regulator part No

    Hi Mayank,

    I've entered your design requirements in the ADI voltage regulator tool and came up with several ICs that you could possibly use depending on your preferred specifications. As an example of a simple solution with less external components,…

  • RE: ADP2384 synchronizing to external clock, but not quite what I expected

    Thanks for the reply!

    I was also expecting the behavior shown in Figure 22. The only difference I see is that the SYNC uses 3.3V logic instead of a 5V -- but the SYNC logic levels listed in the specifications are being met.

    The APS signal shown on…

  • RE: ADP2300 PFM/PWM mode

    Hi Tarzan,

    If you are worried about PFM, then you might consider switching to an ADP2370.  This part has a mode pin that allow it operate in force PWM mode so there is no transition to worry about.  This part will also probably give you better efficiency…

  • RE: ADP2303 ripple

    Jelle,

    The noise you hear is indicative of a couple of things.

    1-possibly not a stable design

    2-layout issues

    3-maybe the inductor current rating is inappropriate

    you may want to use the design tool for the ADP2303 to identify the needed external…

  • 【重点推荐】基于NDIR和PID的ADI气体探测器解决方案和新产品

    NDIR传感器基于吸收光谱学理论:特定气体吸收特定的红外波长,气体浓度与吸收的红外光量成正比。

    NDIR检测器的优势是灵敏度高、 使用寿命长、维护工作量少并且安全可靠,主要缺点是成本高。NDIR气体检测器常用于检测甲烷和二氧化碳,应用行业有采矿、农业、 石油和化工等。



    PID传感器主要由紫外光和电离室构成。紫外光激发气体分子,产生电子和离子,从而获得与电离室中气体浓度相关的电流。

    PID气体检测器的优势是灵敏度高、响应快速、精度高并且安全可靠,但其成本也很高,而且PID检测器的选择性不好…

    ADI公司针对pH计和电导率仪的水分析解决方案

    应用简介

    本文将讨论水分析领域最常见的两种应用:pH计和电导率仪。
    pH衡量溶液的酸碱度。我们知道,大多数生物要求适当的pH水平以维持生命。pH的测量在许多领域至关重要,例如化学处理、纸浆和纸、食物、饮料、制药等等。
    电导率衡量溶液导电的程度,测量电导率是一种极其广泛且有用的质量控制方法。监测水的纯度、控制饮用水和过程用水的质量、估算溶液中离子的总数等,全都可以通过电导率测量来实现。一般而言…
