• AD9830:

    A customer wants to know if it is realy possible to have the 12bit resolution
    (4096steps) with an output signal of 200kHz ?

    We didn´t find this realy in the D/S.


    The ROM on the AD9830 has a 12-bit address. Therefore the 2^32 increments…

  • AD9830: oscillator

    In my design I'm experiencing oscillator
    problems. I'm using AEL1210 integrated
    50MHz oscillator.As soon as the AD9830
    is connected, the amplitude is between
    4V and 5,5V. With the oscillator
    driving a 10k resistor, the signal

  • AD9830 Programming

    Hi All,

    I am trying to program AD9830 in C language. Is there some kind of code examples available? I didn't find anything around on the web. I have my own code that I tried using, but it give pretty weird output, so I think starting from scratch is probably…

  • AD9830 range of REFIN voltage from outside source


    REFIN of AD9830 can come from external source (see description of REFIN on page 5 on datasheet in link). Nominal value is 1.21V. I am trying to find what are minimum and maximum values that can safely be applied to REFIN. In specifications on page…

  • AD650: F/V converter from 0 to 2kHz

    Which values of resistors and capacitors may i use with an AD650JN
    to make a F/V converter from 0 to 2kHz?


    I recommend that you do not use the AD650 with a minimum input frequency of
    0Hz. You should offset the input such that the minimum input…

  • RE: ADF4110 可以脱离单片机工作吗?

    您具体要实现什么功能呢?这类射频芯片基本是需要外部控制的,否则无法实现可变频率输出。我们也有DDS芯片产生频率输出,可以并口控制,但也需要通过引脚去控制, 您可以看一下AD9830。
