I am working with the AD8655. For now I just want to observe its gain characteristics, but am having some trouble. I made a very simple non-inverting circuit and powered the op amp with +/-5V. However, the output does not match the frequency of the input…
Hi Harry ,
Thank you for the information .
Just for the clarification AD8651 is also a CMOS AMP but the current noise Typ is stated as 4fA/√Hz. This device has the almost the same Ib current as of AD8655 .
Though being AD865x family will AD8655 have…
Understood. I'm going to look for available data and perhaps add this to the datasheet.
I'm using ADIsimPE to model a circuit built around the AD8655 op-amp. Particularly I want to know if the model takes into account the input capacitance and input resistance of the device.
From the application note, I understood that the models…
You don't say what supply rails you have, which would help to narrow down the choice. The AD8027 looks like a good starting point, as does the AD8655.
I checked the bonding diagram of AD8655 and yes you are correct that the NC is not connected to the silicon.
If you have other concerns just let us know.
