• AD2S83

    Free PC compatible software is available to help users select the optimum component values for the AD2S83, and display the transfer gain, phase and small step response.

    Where can I get this software?

  • RE: 读取AD2S1210角度与实际相差180°

    感谢回复。我用公司之前的之前的AD2S83试过,同样的激励接法,用图中电路所述的1210读取的角度就是差180。而用AD2S83读取的角度就是对的。

  • RE: Why use AD2S83 at role of the angle indicator? ******** data out

    Hi mnhunter,

                  If it is ok, kindly share your schematic so we may have a better understanding of the problem. You may also check the ground connection. As recommended on the datasheet, digital ground and analog ground should be connected externally and…

  • AD2S83输入由180°瞬变至0°,数据输出异常

    测试AD2S83芯片过程中发现,当输入的信号由180°瞬时变至0°时,AD2S83仍然输出180°,使用示波器测量输入的参考信号、余弦信号和正弦信号,发现信号正常,但AD2S83输出的值保持180°。其他角度90°和270°不存在该问题。从181°顺变值1°时也不存在该问题。

  • RE: 旋变产生的Sin,SinLo 和Cos,CosLo怎么滤波,励磁信号为1K滤波电路怎么搭!

    如果您使用的解码芯片是AD2S83的话,这个是单端信号。AD2S83数据手册中有HF滤波器,可以通过R1,R2和C1,C2来进行滤波。或者在旋变接入AD2S83之前使用有源或者无源滤波器。简单的无源滤波器可以用RC来构成,有源滤波器可以用放大器来做。

    很抱歉,我们现在没有针对AD2S83的参考电路,但是有基于AD2S1210的参考电路,cn-0276. 您可以看一下。

  • RE: AD2S83 free software

    Hi, Tim Starr.

    The software can be found on this thread (http://ez.analog.com/message/41875#41875). Just scroll down and you will find an attachment posted by ShaneO named component-selection.zip. Please take note that it won't run on newer OS but XP…

  • AD2S83: Moving bits

    We have tried to get position from chip. It gives us quite strange output.
    While position sensor is static some bits of output toggles on/off quite
    randomly.Output is like 0x4040-> 0x8080 -> 0xC040 etc.
    Reference freq is 400 hz,…

    Hi Barry,

    Apologies for the delay.

    Please refer to the thread below for the software:

    This will only run on XP machines.

    Thanks and Best Regards,

  • AD2S83_Incremental output with low frequency excitation

    we used AD2S83 before, now he hope our AD2Sxx have incremental encoder output,
    so he select AD2S90. But the frequency of his resolver's output signal is only
    50 Hz. And AD2S90's input signal's frequency is 3 KHz minimum. So it seems …
