• RE: anti aliasing filter for an ADC

    Dear

    I simulated the LPF (using non-ideal parts), the result was terrible and dependent on the components' company! I think I should buy some filters from mini-circuit company.

    I found LTC6400-26 with the fixed gain at 20dB.

    But when I simulated…

  • RE: Amplifying DDS DAC output without using transformer

    Don't use one output. You will get lots of clock feedthrough and junk. Whatever you do, make sure to use the differential outputs to cancel this junk.

    Most op amps don't have the bandwidth and slew rate to keep the 9910's nice SFDR. You might ask…

    The table indicates the supported lanes and interpolation modes. From the data sheet: "A value of yes in Table 26 means the interpolation rate is supported for the number of lanes. A blank cell means it is not supported."
