• AD7606-4的时序

    之前一直使用AD7606,但是由于用不到这么多通道,所以打算使用AD7606-4,现在有些问题。

    我看datasheet上并没有单独提到AD7606-4的时序图,那在读取数据时,AD7606-4是只需读取4个通道?还是需要读取8个通道只不过5~8通道无用?

  • AD7606-4 malfunction

    I'm currently using a AD7606-4 to measure with two of it's channels the outputs from two OpAmps in the +-5V range and forward the result in the serial interface to a fiber optics receiver. However, I am having issues and I don't receive any signals from…

  • Replace AD7606-4 with AD7609 directly

    It seems AD7609 is pin to pin compatible with AD7606 (anyone can confirm this??). So can I solder a AD7609 directly to a PCB designed for AD7606-4?

  • AD7606-4 wrong conversion results

    Hello everyone, I'm in need of some help.

    I have encountered a problem during the usage of the AD7606-4. The read back conversion data via Serial Data Interface SPI (5.25 – 10.5 MHz with CPOL=0, CPHA =1) seems to be wrong.

    For example if I applie…

  • AD7606 placed in AD7606-4 footprint?

    Hi,

    Can I solder 8-channel AD7606 in 4-channel AD7606-4 footprint?

    It is possible to damage the aditional channels by conecting to GND.

    This is the only difference of these ADC's.

  • 关于AD7606-4的ADC值转换

    在设计中使用了AD7606-4来做AD转换

    设置过采样为32倍,输入电压范围为正负10V(RANGE接5V)

    分别接上几个测试电压得到了几个采样值,不知道结果是不是正确?如果结果是正确的,那么ADC值电压值是怎样转换的?

    希望提供转换示例,谢谢!!

    以下为采样结果

    电压              ADC值

    -5V               0x7EDF

    0V                0xFFFF

    2.5V              0x405B

    5V                0x80EF

  • AD7606-4输入短接的问题

    我现在使用AD7606-4做一个50Hz信号的采集。现在出现一个奇怪的现象。因为我只使用了四路中的前两路,所以把ADC3和ADC4的输入端短接到接到AGND上。这样ADC3和ADC4采集到的基本是0电平数据,但是这时候ADC1和ADC2采集的数据就不正常了。但是如果我把3和4的输入开路且悬空,ADC1和ADC2的采集就都正常了。只是在ADC3和ADC4能采到一个正弦的干扰信号。我现在有点迷惑了,是AD7606输入不能短接?还是我的电路其它部分的问题导致了这种现象?

  • How to deal with the unused input of AD7606-4?

    I use one AD7606-4 on my board. All four channels are configured as below:

    But for now, I only need use CH1 and CH2. So I tried several methods:
