Dear All,
I'm using the board Eval-ad7606-6EDZ to acquire analog signal, this is connect with a dsPIC33 by using the serial interface.
I need an input range of +-5V.
This is the connection of the pin
SER/!PAR -> Vdrive
RANGE -> GND

AD7606是8通道
AD7606-6是6通道
AD7606-4是4通道
全是差分信号输入，价格和AD7609不一样，各有优势
If your application does not require all 8 analog input channels then the AD7606-6 and the AD7606-4 are from the AD7606 product family but are 6 and 4 channel versions respectively. However if you are using the AD7606 but dont use all 8 analog inputs…
Q: Are there special grounding considerations for the AD7606?
A: At least one ground plane should be used. It can be common or split between the digital and analog sections. In the case of the split plane, the digital and analog ground planes should…
目前我的板子上设计采用6通道AD7606，但是6通道AD7606目前代理商没货，查阅手册发现，6通道实际上就是把8通道的两个通道接地，所以想问，能否直接把8通道AD7606焊到6通道AD7606焊盘上，当作6通道使用，这种做法有没有什么弊端？另外假如我把整个设计更换，采用8通道AD7606，只用其中6通道，剩余的两通道是悬空还是直接接地？谢谢
Hello, Karen,
Thank you very much for your response!
I understood that
AD7606/-6/-4 Fig 40 is only correct one.
All other Figures below are not correct.
AD7606/-6/-4 Fig 1
AD7607 Fig 1, Fig 36
AD7608 Fig 1, Fig 37
AD7609 Fig 1, Fig 38

Hi,
In the AD7606 product page there is a circuit note CN0148 using two AD7606 although the circuit note focuses on the layout consideration for a DAS solution but here a connection of two AD7606 would have to go through an FPGA. The interface uses the…
Hi Elizabeth,
I cannot read certain labels on your pdf in particular what lines you are controlling with CTL0-7.
Are you giving the part a reset pulse after power up?.
Have you ensured that the correct voltages appear on the ref pins and regcap…
