• Power-on behavior of ADCMP553

    I'm investigating the ADCMP553 for a sampling application, where I would want to power up the comparator for as short of a time as possible (ideally, under 100 ns), obtain the result, and power it down for zero quiescent current.

    How long would I…

  • Driving ADCMP553 with 3.3V CMOS.

    I'm trying to find a robust way to feed the input of a ADCMP553 from a microcontroller.  All systems use Vcc=3.3V.

    The MCU generates a 3.3V pk-pk square-wave.  Frequency is fairly low--about 1KHz.

    I need to attenuate the signal so that it does not exceed…

  • RE: Help with ADCMP553

    Hello,

    I am working on project where i am using a sine wave oscillator which gives output frequency of 200 to 250 MHz with Vp-p voltage of 500mV to 1000mV. I need to convert this sine wave to squarewave. So i chose to use ADCMP553 comparator.

    I connected…

  • ADCMP553 输入端必须端接50欧电阻吗?

    ADCMP553 输入端必须端接50欧电阻吗?针对高速比较器,类似572的手册上必须。

  • ADCMP553中VCCO-2.0V的问题

    最近在做一个电路,其中一部分采用了ADCMP553比较器,第一次接触LVPECL电平,看数据手册上写着在输出端需要加一个VCCO-2.0V的电平,但是553不同于551和552,其并没有VCCO引脚,那么这里的VCCO是和它的VCC相等都为3.3V嘛?那么是不是说在输出端上各加一个1.3V的电平就ok了。

    于是我用ADP1711-1.3产生了一个1.3V的电平通过一个50欧姆的电阻加在了553的输出上,测试时发现1711的输出电平变成了2.6V,后来发现这个2.6V和未加输入和参考时的553的输出电平相等…

  • Bond wire type used in ADCMP553BRM

    I would like to ask for bond wire type used in ADCMP553BRM.

     

    The bond type is 1.0mil Gold Wire.

  • RE: ADCMP533

    Thanks.  I could work,  but the ADCMP553 has a limit of 1.3V on +IN or -IN (Vcc-2V).  So I'll need to experiment.
