• RE: AD5684 not VREF voltage at power on

    Hi,

    The AD5684 does not have a REFOUT, please make sure you are using the AD5684R.

    Cheers,

  • AD5684: Reset behavior

    In our circuit the RESETn pin of AD5684 is tied to VLogic so that AD5684 does a proper power-on reset whenever the power supply is applied.

    However we suspect that in some rare cases the power-on reset does not happen correctly. Is it possible that somehow…

  • RE: How to enable the AD5684 output analog signal by channel A

    Hi,

    Accodding to AD5684R Quick Start Guide》,I think the pin LDAC tie low permanent is OK.

    And I have transmited command 0011 to AD5684,but I still detect any output from channel A.

    I hope you can give me an example code of driving AD5684,or tell me…

  • AD5684 speed

    The search parameter table shows AD5684 having an update rate of 25MSPS. If I take this to mean the output voltage can change with a speed of 25MHz, I don't see how this is possible. 24bit command structure x 20ns min clock cycle x 7us settling time x…

  • RE: AD5683 SPI examples

    Ivan,

    I am using a Microchip PIC18 series to control the AD5683.  I will look at the link you provided for the AD5684.

    Thanks

  • RE: AD5317R internal reference buffers

    Hi Mochi,

    Did you consider to use the AD5684?

    12-bit resolution, similar core than the AD5317R but without internal reference,

    Otherwise... why you don't use a FET.. it is pretty inexpensive,

    Regards,

    Miguel

  • RE: AD5684 Voltage Reference

    Miguel thank you very much for your patience and i'm sorry for being a little pressive, but i still haven't understand what you mean exactly.

    If i understand it correctly, you mean to put before the GND of the DAC a small impedance (for example…

  • 我到现在还不知道启动AD5684这个芯片需要发送什么命令?

         我最近购入了贵公司的一款DAC芯片AD5684,我的电路完全按照贵公司提供的《AD5684R Quick Start Guide》这篇技术文档设计的,然后利用STM32F106CBT6这款芯片的SPI模块发出如附件所示的波形送至AD5684,其中,黄色代表的是时钟信号,蓝色代表的是我向输入以为寄存器发的数据  0001 XXX1 1000000000000000  ,粉红色的代表向SYNC引脚输出的信号。按照贵公司的这篇技术文档,那么我的DAC_A通道输出的应该是1.25V,但是我却无法在芯片VO…
