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
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…
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
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…
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…
