• RE: How to encrypt lib or schematic in LTspice

    Hi Sunil_Kumar,

    SPICE model encryption is performed with the LTspice command using the Windows command prompt.

    Start the command prompt from “Windows System Tools” of the start menu.

    Change to the directory where LTspice XVII is installed at…

  • Any special precautions using LT3045 LT3094 as tracking regulators?

    Would like to use an LT3045 and LT3094 as tracking linear post-regulators to generate +/-3-6V supplies (that track eachother) - with a high-speed opamp (e.g. AD8610 or AD4625-1) in the feedback loop. Are there any special precautions in doing so?

  • What is the difference between AD8610AR and AD8610BR?

    Hi,

    what is the difference between two type numbers AD8610AR and AD8610BR?

    I couldn't find it in the data sheet.

    Thank you.

  • 如何使用ADI官网的spice模型进行仿真

    如何使用ADI官网的spice模型进行仿真 by mu-zi

    新建仿真模型需要lib和olb文件

    1、首先从ADI官网下载SPICE模型,下载的文件为.cir文件。

    2、运行PSpice Accessories 里的Model Editor,并用它打开AD8610.cir 文件

    3、另存Cir 文件为AD8610.lib。

    4、由PSPice Library 文件生成Capture Lib 文件(.olb)

  • 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。

  • RE: AD7466 VIN drops issue

    Hi Jonathan,

    The recommended buffers in the datasheet are AD8510 and AD8610 but I would like to use AD8512 or AD8620 since these parts are pin-to-pin compatible with LTC2055CMS8.

    Regarding the effect on the digital output, I'm waititng for your comment…

  • RE: 看过来,射频放大器基础知识分享!

    说到放大器,不得不提咱们ADI的明星放大器AD8620,应用领域包括安防和监控、扫描设备等!低输入偏置电流、宽带宽JFET精密双通道运算放大器,

    AD8610(单通道)和AD8620(双通道)均为精度极高的JFET输入放大器,具有超低失调电压和漂移、极低输入电压和电流噪声、极低输入偏置电流和宽带宽等特性。与其它许多JFET放大器不同,AD8610的输入偏置电流在整个工作温度范围内都很低。AD8610能够以同相单位增益稳定驱动1000 pF以上的容性负载,在更高噪声增益时则可以轻松驱动更大的容性负载…

  • RE: What is the Input Resistance of the OPA184?

    I've got the AD8610 in the circuit now, and it does well, as far as I've been able to evaluate it. Except that on the -5V input, there is a very noticeable 2-3% error. I think my input is too close to the rails.
