when I use AD5934 measure a resistance,I can get different answer. Ag: a resistance 4K, first time I measure can get4k,but  next time will 4010, I canot find where go wrong. THANKS.

Hi,

I just found out a device AD5934 which is capable of measuring impedance and processing conductivity output. Based on my understanding from the CN-0349 that the device works with voltage excitation with frequency up to several hundreds kHz.I am using…

In Application Note AN-1252 on page 9, the MCLK is divided by 4, but in AD5934 Data Sheet on page 13 the MCLK is shown as being divided by 16. Why this difference?

最近我再设计一个电路板，是用来测定电导率的。我的抄袭方案是CN0349，为了能够抄袭成功，我买了一块CN0349的评估板。 在对这块评估板编写代码的过程中遇到几个问题。真心感谢ADI解答，以及真心感谢用过此芯片网友的解答。

1、AD5934到底有没有内部时钟MCLK？内部时钟的MCLK的频率是多少？我看了很多网友说AD5934的Vout的输出起始频率在30KHz，我想请问，这个输出频率如果是1MHz可以做到吗？我根据AD5934的输出起始频率的计算公式算出来的起始寄存器的值是：64424509…

hi

1. can I set 0 to initial frequency register? if I set 0, will the DAC output DC(0Hz) signal?

2. can I set 0 to step increment frequency register? if I set 0, will it be on constant frequency?

3. If I set 0 to initial frequency register and increment…

Hi,

I have the EVAL-AD5933EBZ to which I have hooked a AD5934 on SCL and SDA pins to try to get data from a different chip.

For test purposes I have tried the following:

- Vpp = 2V, want to measure without external AFE.

- set to external clock, tied…

Dear sir:

               I follow CN0217 of CFLT to test AD5933EVB and every thing is OK as attached file(Impedance & Phase Data-5933) , But , When I soldering AD5934 chip on AD5933EVB and test same condition then it has different result. When I test low impedance…

i am using big 8051 development board mcu c8051f040 . i am  interfacing ad5934 for impedence measurement . i have connected  RFB=220k and Z =220k want to measure but not getting  result  .please help me with example source code . i am micro  c compiler for…

We are going to use AD5934 in our new design, but I do not know how to start with it。 

1) How can I get the lib for AD10 schematic and PCB layout?

2) How to program the IC?

3) In the datasheet, we found there are two probes for measurement, they are…

Hello,

i am working on a project involving the CN-0349 and therefore the AD5934 with a Raspberry Pi Model 3. I already did some tests, which were working fine.

My main problem is to get the right frequency parameters to the AD5934. The data sheet states…
