• ADA4941-1 Is the phase of the differential output internally adjusted?

    Hi,

    I would like to use ADA4941-1.

    So, I have a question. Please help me.

    Question:

    Referring to the D / S of the ADA4941-1,

    the internal circuit consists of two operational amplifiers,

    each of which has an inverting and noninverting…

  • ADA4941-1输出差分电压不对

    根据AD7903中提供电路图如下:

    ADA4941-1供电电压改为+6V和0V,当起始输入信号小于-6.1V时,输出数值不对,将输入信号逐渐增大,差分输出依然保持不变,指导约为-5V时,数据恢复正常,差分输出结果如下图所示,不知是何原因?

  • CN0032电路笔记中,ADA4941-1可否用+9V和-5V供电,并且ADR435也为+9V供电

    CN0032电路笔记中,ADA4941-1可否用+9V和-5V供电,并且ADR435也为+9V供电

    电路笔记中写道。“只要ADA4941-1上的绝对最大值总电源电压不超过12 V,并且满足ADR435的裕量要求,则也可以使用其它电压。”

    是不是说,正电源电压绝对值加负电源电压最大值,不能超过12V?还是说正的不能超过12V,负的不能小于-12V?因为想用固定值的三端稳压电源供电,所以,是不是ADA4941-1用+6V供电,和-5V供电的话也可以满足要求?

  • ADA4941  differential offset

    When I used ADA4941-1, I found my output was the same as the differential offset example in datasheet. The VOP=3.5V and  VON = 1.5V....It makes me confused, and I want to know how to solve it or why it occurs?

  • ADA4941

    我在使用ADA4941的过程中按照数据手册的图49搭建的电路,仿真之后发现两个输出都是正,而且也没有2.4的增益,请问是怎么回事?

  • ADA4941 gain calculations.

    Trying to do the gain calculations for the ADA4941, which look to be quite simple, BUT.....

    I am using a single-ended input, DC-coupled (1.4VDC, mid-rail, single-sided supply 0 - 2.8VDC) with a desired gain of 4, and +/- 1.25V differential input range…

  • Effects of external resistor on ADA4941

    Hi Neil,

    Thank you very much for your reply.

    The provided information is really helpful to me. As you suggested I have decided to use ADA4941( similar to ADA4940 ). I am using ADA4941 (single to differential converter) as similar to the architecture…

  • ADA4940和ADA4941的区别

    目前做一个16/18位AD采集,使用全差分sarADC,如AD7982/AD7915 推荐输入驱动,有ADA4941和ADA4940。

    通过对比两者的性能,发现结构上稍有不同,但是性能上ADA4940全面优于ADA4941,尤其是其带宽特别高,而且共模电压的设置也更方便,请问为什么对于18位应用推荐使用ADA4941而不是性能更好的4940。
