• 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


    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…

    Hi All

    I am looking for LTspice model file for ADCMP553 comparator. Does any one have it.



  • 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.

  • Use ADF4360-9 to track an incoming carrier signal around 150MHz

    I am trying to track an incoming carrier signal around 150MHz for an indoor application. The carrier frequency is one of 50 random channels with a frequency hopping pattern. Most of reference designs with PFD and PLL are for clock generations with a preset…
