• AD2S90 +AD2S99

    Hello.

    Is it possible to use one generator AD2S99 with buffer and four AD2S90 IC's?

    What to do with pins of AD2S99 SIN COS SYNREF? 

    Maybe there are some detailed shematics like in figure 16 of datasheet AD2S90 http://www.analog.com/media/en/technical…

  • AD2S99 and AD2S82A

    Dear Sir/Mdm,

    Please refer to page 6 of datasheet of AD2S99 (you can find the datasheet here: http://www.analog.com/static/imported-files/data_sheets/AD2S99.pdf ). Page 6 describes a recommended connection between AD2S99 and AD2S82A. I tried on this…

  • Amplitude accuracy of AD2S99 vs Input signal amplitude of AD2S90

    We would use AD2S90 for the acquisition of a resolver sensor and AD2S99 for the
    excitation. But the amplitude variations of the excitation in the range of the
    temperature of the AD2S99 is 2V 10% . It Is the same tolerance as SIN and COS
  • RE: Question about AD2S99

    Hello,

    The AD2S99 will generate an excitation output as soon as power is supplied to the device.  There is no way other than powering down the device to disable the excitation signal.  Therefore, if the AD2S99 is to be used in conjunction with something…

  • AD2S99: What is the difference between AD2S99AP and BP versions?

    What is the difference between AD2S99AP and BP versions?

     

    The AP and BP versions of the AD2S99 are two different performance grades. The
    difference in performance is in the frequency and amplitude accuracy over the
    full operating temperature…
  • AD2S90 RDC: Unstable output on A,B encoder output pins

    Hi Everyone.

    I'm currently experimenting with an AD2S90 for resolver-digital-conversion, to provide position feedback for a motor controller. However, the A, B encoder emulation outputs are unstable and keep changing, even when the motor is not moving…

  • 关于AD2S80A芯片无数据发出的问题

    应用情况现在采用的是双通道旋转变压器,粗机和精机比为1:32,采用两个AD2S80A分别采集粗机和精机的数据,

    采用AD2S99作为旋转变压器的正弦激励。

    现在有一个问题,采用FPGA读取AD2S80A输出二进制数据,当FPGA设置采样速率为500K时,数据没有问题,当采样速率设置为50MHZ时,精机的芯片会出现死机

    不发出数据的现象,请问这个是什么原因引起的这个问题。

    设备开发——模电篇

    早在大学就学过模电,真正需要用的时候,只留给我二极管,三极管,放大器这几个淡淡的印象,书到用时方恨少。

    第一个涉及到模电的事是几年前要设计一个信号源,信号脉宽可由单片机或外接信号源控制,纯数字电路逻辑上并不复杂,不过脉冲幅度需要达到±80V。这归根到底难在±80V电压和数字信号的以小博大上。超过36V我就害怕了,于是想到了电路仿真,这也是我第一次真正使用Mutisim了。该软件是大名鼎鼎的EWB的升级版,用的人多,资料还算丰富,半天就可以入门了。后来听说这个软件被NI收购了…
