• AD8552

    你好!
    目前我用AD8552做了一个全波整流电路,电路如附件所示,目前Test1点的电压小于-0.8V(即 -0.9V),则Test2电压将不再保持为0V,这不符合单电源电压跟随器的特性,这是什么原因造成的呢?是芯片内部保护吗?为什么LTspice XVII上不会有这个问题?我该怎么解决这个问题? 请您尽快回复。
    谢谢!
  • AD8552 spice model

    Hi

    I found AD 8552 spice model not working properly.Initially the file was not reading , then I found  there is two "dots' in before "subckt" declaration and I changed it and my spice program ( LT Spice) started reading. But I got a model without any…

    The circuit you describe using 3 AD855X opamps will not work. The gain is too
    high and even with a common mode voltage equal to mid-supply, the first stage

  • RE: How to reduce effect of temperature to relaxation oscillator (using AD8542)?

    Hi Harry,

    I've tried with AD8535 and AD8552 but the problem is not fixed.

    The output is still effected by temperature. And I found new problem.

    With the same circuit (just change opamp), there are the different frequency output

    Mark,

    Please see above additional questions,

    BTW:

    LTC6078 has 25uV maximum offset voltage, as same as OP97

    I simulated in SPICE and it should work.

  • AD822: Phase reversal

    Tha datasheet states that the opamp AD822 do not phase invert the output signal
    when the input signal exceeds the supply voltage, but it does. How can that be?

     

    It is important to distinguish between over-voltage protection (i.e. the
