• How to run AD7606-4 with minimal pins?

    I want to run the AD7606-4 with as less pins as possible.

    • Which pins are really necessary?
    • Which pins do I not need?

    I will use 2 inputs for 2 sensors. I just want to convert the analog signal into a digital.

  • AD7606测量结果为实际值的4 - 4.5倍

            首先,我在前一块板子上做实验的时候因为没有去耦,导致CONVSTX信号有干扰而致使采样频率很靠近250K,但是采样得到的数据都是正确的,所以我认为编码转换上我应该是没有问题的。

            后来我修改了板子,这次没有干扰了,采样频率50K,没有过采样,8个通道实际使用4个,通过示波器观察应该都没有问题。

            然后进行测量,结果发现测量的正值总是实际值的4.5倍左右,负值总是实际值的4倍左右。

            比如我测一个50Hz的0.2Vpp+0.2Vdc的方波,结果低电平是0.47V,高电平是1…

  • AD7606 Input bias voltage

    Hello colleagues!

    I have the issue with 1.8V bias on each channel of analog input of AD7606. Same question I see also in FAQ and in other topic of EngieerZone but unfortunately I don't see the answer there. Here is links:

  • RE: 4*4 Tx/Rx Beamformer

    External LO has a divide by 2 inside. This divide by 2 is random, and it's randomness is determined by the LO input power. (if LO goes away, and comes back, then the phase of the divide by 2 is random). This randomness also depends on power up cycles…

  • 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 - powerup sequence

    Q: Is there a power-up sequence that I should follow in operating the AD7606?

    A: Page 11 of the AD7606 datasheet shows that VDRIVE is dependent on the AVCC so it is worth noting that the AVCC must be powered up before the VDRIVE.
