• AD5546

    在使用AD5546做精密衰减的参考电路中,有一个反馈电容C6。这个电容值的大小应该如何随频率变化呢?

    在参考输入是正弦波频率是150KHZ~1750KHZ频段的时候适合用多大容值的电容呢?

  • AD5546评估板

    你好

    我买了一块AD5546的评估板,需要与FPGA连用,进行模数转换,有没有verilog程序可以借鉴一下啊??

    谢谢

    If the reference input is an AC signal as stated below in figure1 and I still
    would like a bipolar output, but I don't use the U2A OP2177, and float the R1A,
    ground the RCOMA, then apply AC signal directly to VREFA. Is this  connection…
  • Harmonic performance of AD5546 DAC

    Hi. I am AD5546 DAC for output 36 KHz Sine wave. I am using this in four quadrant mode with ADR03 reference in line with data sheet. I have conversion frequency of 1152 KHz. So 32 samples per cycle. But its harmonics performance is poor, just 30 dBc.…

  • SDP-B with AD5546 documentation

    Hi,

    I am trying to write my own application for the SDP-B in C/ASM for use with the AD5546.

    I have VisualDSP++ and the ICE-100B emulator. So far, I have followed the instructions here: http://ez.analog.com/docs/DOC-1933 (the example code there does…

  • AD5546 with SDP-B LabView source?

    Hi,

    I'm using the AD5546 with the SDP-B and would like to write my own LabView software to control the output automatically (ramp up/down at will). Is the LabView source for the provided AD5546 software available? Or some way to call the software from…

  • Series or Shunt Voltage Reference for AD5546

    Hi I am following AD5546 evaluation board schematic for my design. But I need a reference of +12V to generate 0 to +12V for my application. But I could not find any fixed higher voltage references to replace the +10V ADR01BKSZ used in the board. I have…

  • Re: SDP-B with AD5546 documentation

    I have one other question. I would also like to use a DAC on Connector B.

    Is it possible to do this? I tried to write to Async Bank 1, with the same method that worked on Connector A, but it didn't work.

    Also, could it be possible to use both at…

  • AD5546实现信号衰减设计疑问

    我现在想利用AD5546实现信号衰减的功能

    原理图设计见上图所示。

    输入信号是正弦波形,

    目前AD5546的连接方式是二象限模式,但是没有外接数据手册中推荐的运放,后级的ADA4941作为外部运放实现I-V转换。

    时序按照datasheet中给定的时序图,

    并且尝试了复位信号在前,读写信号在后的时序,

    脉冲宽度都在40ns以上,

    但是不管在参考端输入波形或者电平,在输出端都得不到正常的输出,改变控制字输出也不会随之改变。

    不知道出现这种现象的原因是不是因为电路设计没有完全按照参考电路设计…
