• RE: AD9674 TGC Gain input driver

    Thanks Hugh, sorry for the late respond.

    I prefer below solution:

    cn0180(ad8657 change to ADA4896-2) + ADA4938

    Because I can not understand fully for other choices. It is high risk for me.

    For "The AD5429 has 2 channels of current output, you…

  • AD5429 PGA circuit problem

    I have designed a two channel programmable gain control circuit using an AD5429 dual DAC.  The circuit is based on the recommended circuit shown in Figure 42 (Page 18) of the Rev E (latest) data sheet with the exception that the O2 pin is biased to +2…

  • AD5429: DAC not responding to sending of serial word

    Being about to evaluate a design with an AD5429, I have not succeded
    establishing the SPI communication.

    Detailed configuration:
      variable-gain amp
      SPI active SCK edge: H-to-L transition
      update mode: asynchronous
      Fsck<10M…
  • Query on AD5429 - 8 bit DAC

    Hi,

     

    I need a variable differential reference which can generate voltage ranges from -10V to +10V. So, I thought of using a DAC to generate those variable references.

    Since I need a differential reference I have selected a 2 channel DAC, AD5429. While…

  • AD5429: DAC does not start up correctly sometimes

    I have a problem that AD5429 can not start up correctly. The start up fails once or twice every 10 times power up.

    In that case, DAC output does not change even tough applying any command and power up command. Does not respond to program (Clear DAC output…

    Hi Sai,

    Attached is the PCB layout and gerber files for the HMC812LC4 Evaluation Board. This is a simple EVB circuit, we do not have the user guide or schematic diagram. The layout follows the same application circuit as shown in the HMC812LC4 datasheet…

  • RE: Synchronizing DDS with ADC for FFT

    Hello,

    I can offer youy a few options but suitability depends on the LED requirements.

    • You could use a DDS (like the AD9838 - single channel only) - and synchnoise multiple devices using the reset pin as shown in the AN-587 apps note. Different part…
  • Daisy chain issue with AD5415

    If you are using or plan to use the AD5415 12-bit DAC chip in a daisy-chain configuration, you need to read page 20 of the marked up data sheet attached.  If you are using the SDO output of even a single AD5415, then you also need to see the erratum marked…
