• LTC1666 - Input clock source

    Dear all,

    I am currently working in order to create a digital wave generator using:

    - FPGA

    - LTC1666 DAC (https://www.analog.com/en/products/ltc1666.html)

    The timing diagram in the datasheet is confusing - it shows sample N-1 and N+1 as being within one…

  • RE: LTC1666 - Vref - input resistor

    Yes you can use a higher voltage, just adjust Rset accordingly. 

    It is not necessary to put resistors between the FPGA and LTC1666.

  • LTC1666 - MiniCircuit transformer OUTPUT circuit.....

    Hello, I am designing pcb for LTC1666 DAC. At differential transformer Coupled Outputs circuit, datasheet recomend a T1-1T transformer type.

    What if i want to use a splitter? like JSPQ-65w+ 2 Way-90 50ohm. How can i remplace T1-1T transformer? or use…

  • LTC1666/LTC1667/LTC1668 Power on reset value?

    I designed a board using an LT1666 and I am wondering which value does the DAC holds at startup.

    It seems to me that is powers up at 0xFFFF.

    The datasheet is lacking this information.

    Thanks.

  • Questions on how to use LTC1666's I to V convertor OP-AMP

    My customer wants to use the LTC1666 as shown in Figure 8 below.

    However, I would like to use Vout in the range from 5V to 0V, so please check what to do.

    Waiting for your reply.

    Thank you.

  • LT8330 at 8v-40v -/+15V - Suitable to source Op Amp on dac's output circuit?

    Hi , im needing to use a +/- Source to energize dac's output circuit as purposed in LTC1666 (page 15), My idea is to use LT8330 AT 8-40V TO +/- 15. Is this integrated circuit suitable for this application? Any available recommendation is welcome. …

  • Switching Power Supply to Source DAC and Analog ouputs

    Hello dear fellow,

    I'm designing my own Eval Board which includes a DAC LTC-1666. As I saw in many Kit, this boards are usually sourced by an external Supply. My idea is to have the option of external sourcing and by jumpers, select a power switching…
