• AD822 Output on Multisim Simulator

    Hi!

    My name is Claudio, I'm a hobbyist and this is the first time I'm writing in this forum.
  • AD822 Single-supply capability

    Hi,

    The single supply voltage spec has been changed from 3V~36V to 5V~30V since its data sheet revision I was

    released. Do you have any documents like PCN announcement about it? When the revision I data sheet was released?

    Regards,

    Kazu

  • History of AD822 data sheet

    Hello

    I am tracking the history of the external dimensions of the AD822 at the request of the customer now.

    I read that the AD822 (SOIC) has changed the external dimensions five times in the past and also converted to halogen free.

    I'd like to check…

  • Thermal resistance θjb & θjc for AD822

    Hi,

     

    I would like to know thermal resistance of junction to the bottom (θjb) and junction to the case (θjc) for AD822

    The above data is not available in Datasheet. Only find θja.

    Data will be helpful for thermal analysis. Appreciate…

  • AD822 (A), looking for modern version for this

    Hi

    AD822 is quite old (1995 I think), I wish to find replacement of more modernise version.Please don't ask me why(!)

    The key parameter is +5V, FET/CMOS, low frequency, low gains circuit (noise not important), good rail to rail, good I/P range to…

  • AD822跨阻放大电路输出波形失真

    大家好,我用AD822搭建了一个跨阻放大电路,可是输出的波形竟然是失真的,我真的不知道哪里出问题了。两个200k和100uF的钽电容构成高通滤波器,2.2k和4.7nF构成低通滤波器,输出波形失真了,如下图所示,有时候波形上出现的小峰会更多。请教大家,该怎么解决?谢谢

  • AD822's Input Impedance - best way to measure and variation from typical spec?

    In the datasheet the AD822’s input impedance is a typical spec. Do you have any
    more information regarding an estimated variation of this impedance? What's the
    best way to measure this parameter?

     

    We do not measure the input impedance…
