• AD7606 resolution

    Hi,

    I used AD7606-4 detect voltage signal,I found the resolution just can achieve 2mV.

    1.I used AFG31152(signal generator ) to create the voltage signal. when the input signal change 1mV, the output code of AD7606, did not change. But the  input signal change…

  • On EVAL-CN0313 there are three different circuits that offer various protection levels for IEC61000-4-2 ESD, IEC61000-4-4 EFT and IEC61000-4-5 Surge. Why is there different protection circuitry used for Surge Level 4 compared ESD/EFT level 4?

    The EVAL-CN0313SDPZ is a certified EMC Compliant RS-485 Interface Design Tool. 

    The main reason for the different protection circuitry is related to the difference in energy levels associated with each of the transient waveforms. According to the IEC61000…

    Hi,

    There will be a degradation in the conversion results. This has been confirmed on the AD7606-4 evaluation board under nominal conditions and at a temperature of 25C. Not having the correct decoupling may cause the regulator to ring or oscillate. There…

  • The measured value of AD7606 is about 4 times the actual value

    Hello,

    We would like to use the AD7606 for voltage measurements (only use 4 channels, no oversampling, parallel interface mode), and control it by FPGA.

    First time, I forgot to decouple so there is an interference on CONVST A/B, leading to wrong throughput…

  • 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…

  • AD7606-4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?

  • 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.
