  • 关于ad8620线路接法

    本电路图是功率稳定完整描述图，图中绿色标注部分为接口的相关说明，基本原理就是通过光电二极管采集的电压同设定光强电压做对比，最终将输出电压输送给光栅，以此来调节激光器的光强。

    然而涉及到芯片的一些接法实在不知道原理是什么，因为是从其他控制器直接copy过来的板子，所以不知道有些接法不知道是对是错。

    请教大神描述一下一些接法原理：ad8610的接法网络，tl084, ad823，还有ad712的接法，这些都是为了做什么呢？

    电路图附件表示中。其中ad8610部分在最下方。

  • using AD8620 as cross-coupled single-ended-to-differential converter

    I use AD8620 as a cross-coupled single end to differential coverter as following figure, but it doesn't work. what should I pay attention to? can I use other general OP (such as LF353D) to replace the AD8620? I need +/-12V power supply and both of them…

  • RE: 偶然发现，大家都辣么爱AD8620！

    说实话，AD8620是唯一的低功耗（Iq=3.5mA），高压摆率（SR>50），高带宽，低噪声，高容性负载驱动力各个指标层面上最优的产品了。。。但是就是价格比较感人，我们的设备原先使用的AD8066，后来换了ADA4610-2发现压摆率可能上不去，很有可能要吐血上AD8620了，一个板子8片。

    真心不错的产品。要是ADA4610的压摆率能到35（仅仅增加10，为了与AD8421匹配），我们就能用了，哎，差一点心疼死人啊

  • RE: 请教AD8620

    您用过AD8620吧，是图片中的电路吗？我在应用中发现VIN最大输入时±7.5V，大了反相端会失真，您遇到过此问题吗？

  • 超级发烧友分享：N张大碟视听AD8620有感

    最近玩音频运放，看到网友分享的AD8620试听评价，很发烧很专业！ ADI的专家怎么看？大家怎么看？

    迎来了两只AD8620的运放，几经辛苦焊上镀金脚座后，便迫不及待地插上cd机，现在谈一谈这对ic的听感：

  • RE: AD7466 VIN drops issue

    Hi Jonathan,

    The AD8512 and the AD8620 are not pin-to-pin compatible with LTC2055 so I would not like to use them.

    I'll try to test with AD823A.

    Regards,
