• AD826发烫

    使用AD826做简单的交流恒流源，用的是豪兰德电路。接不接负载，运放都很烫，是什么原因呢？

  • AD826 heats up

    At the moment, our department has released a filter circuit board, one of the main components of which is the AD826.

    In our circuit, the power is from a 30V block, with a midpoint of 15V. Scheme in attachment.

  • AD826 hot issue

    Dear Specialists,

              Now we are following below schematic after DAC. When power on we find AD826 is very hot( no load ), we change ICs and still meet this issue, the samples are purchased from on-line market e-Luomeng , can you kindly help to advice…

  • What is the single supply rating for AD826?

      Data sheet says it can operate to  +36V, but absolute maximum is  +/-18V.  Does that mean plus voltage can't go above 18V?  My colleague says yes.  I think the difference between -Vs and +Vs can't exceed 36V.  What is the answer? 

  • AD817 and AD826 what is the output short circuit current duration?

    I could see from the datasheet that the short-circuit current is 90mA but what is the max duration? In the datasheet, it says 'See Derating Curves'. I don't understand what that means. I am driving capacitive loads directly (16 source pins of AD1434 quad…

  • Single 5V supply AD826 Hot and not working close to zero

    Dear Sir,

    We are using AD826 as buffer before an ADC. 5V DC single supply. Gain is 1.

    When input is close to zero or zero (not negative however) we experience inconsistency on the output and AD826 is heating. Seems to work as we increase input voltage…

  • why wont my AD843 work inplace of my AD826 in my audio pre-amp?

    why wont my AD843 work inplace of my AD826 in my audio pre-amp? I thought both being 8pin and the AD843 recommended as great sounding that it would swap out for the AD826 i had in there; but the AD843 won't pass audio through it to the output of pre-amp…

    杨老师您好：

          我查阅放大器手册时，尤其3DB带宽在10-50m赫兹之间的手册时，没有看到上面明确表明是电流反馈型还是电压反馈型放大器；有的放大器，比如AD826,工作的压摆速度非常高，350v/us；但是手册上说是高速电压放大器（“The AD826 is a dual, high speed voltage feedback op amp.”）；但是其配置的反馈电阻非常低，所以感觉有点奇怪；希望杨老师能指点一下，如何来判断一个放大器是CFA还是VFA。
