• LTC2757 update rate specifications

    Hi,

    A few questions about this DAC:

    1) Based on the timing characteristics of the digital interface for Vdd = 3.3V, it should be feasible to update the LTC2757 at 16.66 MHz.  However, if the output settling time specification in the datasheet is 2.1 us…

  • How to interface LTC2757 with LT1010 buffer?

    I would like to use an LT1010 output buffer:

    ...with the LTC2757 DAC:

    The LT1007 as shown in the buffer schematic will be substituted for the LT1468 shown in the DAC schematic. My questions are:

    1. Where should I connect the DAC's Rfb input? Should…

  • Best DAC for DDS Waveform Generation between 1-100kHz (Ultra precision, Ultra low distortion, low noise)

    Hi

    If you have to build waveform generator and choose a DAC to generate ultra pure (over 100dB SFDR) ultra precision (below 5uV offset), ultra low noise (below 10nV/rsHz) 10khz sine wave what would you chose ?

    My first choise is LTC1668 + composite…

  • How to estimate LTC2757 output voltage noise density?

    I am trying to figure out how to estimate the total output noise voltage density when I connect a LT1460 reference, LTC2757 DAC, and a LT1468 output transimpedance amplifier together. The datasheet simply lists "output voltage noise density" with no information…
