    TI Thinks Resolved
    Part Number: DAC5681 Hi, Do we have 1/f noise data for <1KHz range? Thanks. - YY

  • DAC5681: Please let me check about required specification

    TI Thinks Resolved
    Part Number: DAC5681 Please let me check about DAC5681 required spec for two points below. ①About CLKIN voltage, datasheet P10 is described 0.4V_min and 1.0V_typ. 　Is differential voltage 1.8V, no problem? Is there max voltage? 　If 1.8V is problem, is…

  • RE: Setup for generation and post processing of a set of tones around 125 MHz

    Yes, about producing and sampling simultaneously, controlled by a single PC. We have tried with TSW1400 EVM controlled by HSDC GUI and connected to DAC5681 or ADS5463EVM, but your support service explained us that is not possible to control both simultaneously…

  • DAC5681 gain drift

    TI Thinks Resolved
    Other Parts Discussed in Thread: DAC5681 I'm looking into a high speed DAC for an Infrared projector. I need 14-16 bits of DC accuracy and a full scale settling time of around 100ns down to 1LSB. The DAC5681 looks promising but I have a question about…

  • Setup for generation and post processing of a set of tones around 125 MHz

    TI Thinks Resolved
    Other Parts Discussed in Thread: DAC5681 , ADS5463EVM , DAC38J84 , 66AK2L06 , ADC12J4000 We are interested on the generation of a set of tones in I and Q components (i.e.: 10 tones, with possibility of tuning the frequencies separately) in the range 100-150MHz…

  • TSW1400+DAC5681 to generate a sweep frequency signal, from the 150M-250M

    I would like to use TSW1400+DAC5681 to generate a sweep frequency signal, from the 150M-250M. scan time of 8 Microsecond, triggered by an external pulse signal. I would like to confirm that an external pulse signal, triggering a sweep frequency, the…
