Hi all,
I would like to use the ICL7652P (8-pin device) for the first stage of an analouge integrator.
From the datasheet you see the functional block diagram and there you are told to connect the capacitors CXA and CXB to VDD- or C Return.
For my given PCB I connected them to C Return and this results in utter malfunction.
According to the block diagram I should expect a low impedance connection between C Return and VDD- but this is not true.
So next step was to short C Return and VDD- on the board and now the circuit works but with very bad performance concerning noise.
Is there a typo in the datasheet or do I miss here anything?
Thanks and best regards,
Gerald
