• 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 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: 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…

  • 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…

  • RE: How to synchronize two AD9835s?

    Hi David,

    The AD9835 does not have the Reset pin required so you will need to look at either the AD9834, AD9830 or AD9831. FQ_UP has the same functionality as the FSYNC pin.


  • RE: VF Converter

    Hi wallman16,

    We do not have VFC parts with a maximum output frequency of 5 MHz.  The DDS parts such as the AD9830 could be used. The DDS part generates a waveform from a digital code. An ADC would be required to convert the voltage to a digital code…

  • DDS for space or Radiation Hard Specifications

    We need DDS parts for the high reliability and rad hard space  market.
    Will ADI never produce such parts and if not what do you suggest
    your customers to do?

  • 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…
