• ADCMP581 Power Consumption

    I just wanted to ask the total power consumed by ADCMP581.

    As per data-sheet:

    ADCMP581 (NECL)
    Positive Supply Current: IVCCI: VCCI = 5.0 V, 50 Ω to −2 V: 6 mA
    Negative Supply Current: IVEE: VEE = −5.0 V, 50 Ω to −2 V: −25 mA
    Power Dissipation: PD: 50 Ω to −2 V: 

  • ADCMP581手册参数请教

       您好,我在查阅ADCMP581手册的时候发现581的最大输出电流为-40mA(手册第6页),我不太理解的是581是差分输出的比较器为什么会出现负的输出电流?难道是一端为-40mA,另一端为+40mA么?

           然后就是我现在的应用十分关注比较器的输出电流,但是手册中只给出了最大输出电流我想知道如何能获得更详细的信息,以及比较器驱动电容时的输出响应,如果使用Multisim仿真结果的可参考性强不强?

  • ADCMP580/ADCMP581/ADCMP582 input nose model

    Can you please provide input noise models for ADCMP580/ADCMP581/ADCMP582?

     

    We do not have any models for available for the ADCMP580/ADCMP581/ADCMP582.
    However, the datasheet does contain typical jitter numbers which  may help.
  • What's your recommend ECL Receiver/Driverfor Voltage Comparators ADCMP581?

    Dear Sir/Madam,

    As for your Voltage Comparators/ADCMP581,I have a question for you.

    I think that ADCMP581 cannot connect the device ECL-input-type, because the output of ECL is RSECl level.
    So if I would like to connect your ADCMP581 to another device…

  • Input voltage of absolute maximum ratings for ADCMP580, ADCMP581 and ADCMP582

    Hi,

    I have a question about ADCMP580/1/2.

    When I see the absolute maximum ratings, Input voltage should be between -3V to 4V.

    I believe this means ADCMP58x aren't broken when users use within the ratings.

    My question is that the AMR of input voltage…

  • RE: What is the random jitter specification of ADCMP566 dual high speed comparator?

    Hi Joshua,

    The ADPCMP566 is an old part and hasn't undergone the same evaluation as ADCMP581.

    We don't have enough test data to provide regarding the random jitter specification. We can however do some evaluation for a typical specification but…

  • RE: Questions for your ATE device ADCMP580

    Hi, Kaos.

    ADCMP580, ADCMP581 and ADCMP582 have the same datasheet which you can find here. The main difference of these three comparators is the output driver wherein ADCMP580 is CML, ADCMP581is NECL and ADCMP582 is PECL.

    But since you need the tr/tf…

  • RE: ADCMP580 Latch Enable/Disable

    HI Fabian,

    The datasheet description is consistent from table 5 and Using/Disabling the latch feature section (page 12).

    On table 5, it states that in order to disable the latch feature the following configuration must be used:

    LEB = Low
    LE   = High

    On…

  • RE: ADCMP582 Comparator: Disable Latch Feature.

    Sorry to kick a two year old thread but I'm having ADCMP582 problems myself, so I'm scrounging everything I can find.  @DavidLee is exactly right, nothing about the description of the latch input makes any sense.

    In the descriptive text on page…
