  • RE: Problems interfacing AD623 with AD8561 comparator.

    Hi Christian,

    A few questions for you:

    - What are the supply voltages for the AD623 and AD8561?

    - What is the AD623 reference voltage?

    - What is the gain of the AD623?

    - Can you elaborate on "this seems to cause problems with the AD623".…

  • RE: AD8561比较器的问题

    是输入信号出现尖峰还是输出信号出现尖峰?是否可以将AD8561的输入与其他芯片端口,单独测试AD8561。

    Is there any information out there for the LET threshold for the AD8561S? Thanks in advance...

  • AD8561 Hysteresis

    hello,

    In the AD8561 datasheet, page 8, a hysteresis circuit is shown:

    The capacitor CF is added to introduce a pole into the feedback network.

    The calculation for this pole is: 

    Is this formula correct? In the formula, I would use R1 instead of R2.

  • RE: Comparator stability - AD8561 versus LT1711

    Hi gil_he:

    Do the oscillations occur when the inputs are near zero cross?   That could actually be a noise problem rather than an oscillation, and might be fixed with a little more hysteresis.

    The LT1711 is quite a bit faster than AD8561.  The LT1713 is…

  • Using AD8561 for 100kHz or higher frequency Sine to Square Wave Conversion (zero crossing detector)

    Hi, I have a question about using AD8561 for 100kHz or higher frequency Sine to Square Wave Conversion.

    The comparator I'm using is AD8561 and the circuit diagram I set up on breadboard is

    Inline image 1

    And the response I get is as follows, with sine wave…
