• AD711替代方案

    你好,

            咨询一下大家,AD711芯片有什么替代芯片或方案,OP07货OP177可不可以完全替代AD711? 

     

            感谢各位!

  • RE: OP-177

    Hi again. can ı ask you another question. When ı read op177 datasheet and ı see typical offset voltage is 40 uV but ı set up test circuit my offset voltage 5 mV. Maybe this is a problem. What can ı do for this.

  • RE: ad8138驱动AD7357,AD7357基准输出变为2.9V?

    还是上原理图吧,你用参考设计,是哪个图,说明一下

    若是数据手册中的Figure 21,AD8138和基准没有关系吧,经过OP177隔离了

  • RE: short pulse amplifier

    what is Y1 in your schematic. I do not follow exactly what you are doing but you can look at figure 36 of OP77 datasheet hwich gives you detection and amplification. You may need to do adjustment for your needs.

  • Replacing AD624 with AD8295

    Hi all,

    We are using AD624 Instrumentation Amplifier for our signal Conditioning Application for Strain gauge based sensor like Force and Torque Sensors.  Here we get Voltage in mV and we are using AD624 as IA and then a second order Butter worth filter…

  • RE: 微伏电压信号放大电路

    细看了下OP177的GBW,600KHz,若G=200,BW就只剩3KHz了,处理0.5KHz信号余量不大的。

    OP27这款经典OP07接班人,GBW有8MHz。

    建议用官网推荐的替代型号ADA4004,ADAxxxx是ADI后续主推型号。

  • 关于运放开环增益非线性的问题

    1、在运算放大器应用技术手册(OP AMP APPLICATIONS HANDBOOK)及OP177的手册中写到OP177的开环增益非线性的测试电路如下图:

  • query regarding Electric characteristics of AD5544 current output DAC

    Hi,

    1. In the data sheet of AD5544 it was mentioned that the static performance parameters like INL, DNL, Full scale gain error are the values correspond to closed loop system using an external precision I-V converter amplifier (OP177).Would like to know…
  • RE: LT6235 op amp hangs in LTSpice simulation

    Hi Hooman,

    I think this is very simply explained. I know that any type of analysis consists of successive stages. When running any type of analysis, the first step is always to search for a DC operating point, for example.

    These steps can be canceled…

  • Measuring multiple current ranges simultaneously

    Dear Fellows,

         We have a task to measure a current range from 1uA to 300mA. The measurements must be completed without switching the range with a BW of 250kHz.

         The proposed solution is:

    • Use of a 10 ohm shunt resistor
    • For high range use a high…
