• AD9706 OTCM

    We are using the above part to drive a zero-IF IQ modulator that requires a DC bias of 1.15V. We have set the full scall current to 5mA (Radj = 6.4K). We have set the OTCM to 1V (from REFIO). We have a load resistance of 118 ohms. We are unable to achieve…

  • RE: AD9238 ADC Voltage Input

    Hi -

    The AD9706 output is a current. The voltage at the output pins should be +/- 0.8V relative to OTCM.

    Thanks,

  • AD9706 Output buffer question

    Hello everyone,

    I'm currently working on a low power chirp generator.

    Someone before me working on this, used the AD9752 (12-Bit).

    I would like to replace the DAC for an AD9706 (12-bit), on the output I'd like to use an

    differential to single…

  • RE: High speed DAC with serial LVDS interface

    The AD9706 matches the precision and DAC update rate you desire, and is probably the closest we have to what you need. Its interface is a parallel CMOS interface.

  • RE: Is it necessary to buffer the output of the AD9649?

    Hi Andre -

    Series terminators are a good idea for the AD9706 data input signals. Ideally they should be close to the signal source and have a value of 25 ohms.

    Thank,

    Larry

  • RE: Max time to power back from sleep mode of AD9740

    Thanks, I agreed.

    BTW, please let me additional inquiry.

    In a datasheet of AD9705, there is resemble sentence "The AD9704/AD9705/AD9706/AD9707 approximately 5 μs to power back up, when 3.3 V AVDD is used."

    Can I suppose that the max time…

  • AD9706 OTCM pin powered from ADP223 LDO

    We have a development card using 2 x AD9706 DACs to drive a zero-IF IQ modulator that requires a DC bias of 1.15V. We have set the full scale current to 5mA (Radj = 6.45K). We have set the OTCM to 0.5V, derived from a ADP223 Dual LDO. We have a load resistance…

  • RE: How to convert 12 bits Serial LVDS to parallel 12 bits for DAC interface?

    Dear Mr. Deljones,

    I am using the parallel input DAC (AD9706). My FPGA is giving a serial output which am converting to parallel digital inputs for the DAC using an intermediate De-Serializer. The de-serializer gives a clock output based on the frequency…

  • RE: 求ADC及DAC芯片选型

    您好。很抱歉,没有完全满足您要求的器件。ADC请参考AD9626,AD9230。 但是是差分输入,输入信号幅值也需要调理。DAC可以参考AD9706,AD9742等,是电流输出的DAC
