• ADG1434(YRUZ) Over-voltage Issue

    We are using ADG1434(YRUZ) biased at +15V for Vdd, -15V for Vss. The power input for the chip is from an APS rated at +/-15V and +5V with 10% trim (min). 

    During our experiment, we use several sets of chips, and one set of the chips was burned.

    We tried…

  • ADG1434 Backfeed to Vdd when powered off

    b8a2a87b686df095b4eb3519363b4173.html0118.b8a2a87b686df095b4eb3519363b4173.htmlI am using the ADG1434 biased at +15V for Vdd, -15V for Vss. This switch is being used to multiplex RS-232 data (+/-12V single ended).

    The switch works great when it's powered…

  • Alternate IC for ADG1434 with power off protection

    Hi all,

    We are using Quad SPDT switch ADG1434, in one of our designs.

    In our design, the input lines may be driven even when the power is off.

    Below disucssion suggests that ADG1434 is not suitable for such applications.

    ADG1434 Backfeed to Vdd when…

  • RE: Does the LTspice model of ADG1434 also model the CS/CD (ON/OFF) capacitance?

    Hi, paulplusx.

    Our switches and multiplexers have the following parameters included in the LTspice model:

    • On-Resistance (The twin-peak curve at +/-15V for the ADG1434, but operational in the entire voltage range of the device)
    • Charge Injection
    • Timing…
  • About characteristic change by temperature change of ADG1434

    Hello,

    Could you let me know the following information about ADG1434?

    1. Does the pin capacitance (CD,CS) change significantly with changes in temperature or input voltage?

    2. Fig. 22 of the data sheet P12 is a figure at 25 ° C, does the characteristic…

  • offset voltage problem with analog switch ADG333A, pin-compatible substitute?

    Hello,

    I've got offset voltages of 0,2V with a device containing ADG333ABNZ. Do the pin compatible newer versions like ADG1434 or ADG5434 correct this?

    Best regards,

  • 模拟开关不一定完全替代继电器,ADI的攻城狮来讨论一下?(转)

    转一篇文章,原文如下,不知道ADI的工程师们怎么看我们一起探讨下介个问题吧

    在最近的产品调试中,发现了许多在实际设计中不难发现的问题,在本文中我从自己的实践经验中总结某些结论,希望给大家的电路设计带来某些帮助,这也能使大家在器件选型时考虑到这一点,以免在设计调试时出现类似我们的悲剧。

    我们选的模拟开关依然是ADG1436和ADG1434,这两类器件在以前的博客中做过简单的介绍,在这里我还是挑比较明显的字眼:

     

      这句话什么意思呢?这是ADG1434、ADG1436这类模拟开关的应用中第一个提到的字眼…
