FAQ
Hi,
The AD8515 has wide range of differential signal as seen on Absolute Maximum Rating.
The input may also exceed the supply range as discussed on the Theory of Operation.
Figure 27 also displays an input of 3.2V and a lower supply range of +/-0.9V.
Please…
Hi
We are using the AD7746 and AD8515 to measure a capacitive pressure cell, does anyone have any experience with using conformal coating on these components and circuit?
Could DCA scc3 conformal coating effect its performance?
Thanks

Hi!
I would look at the AD8515. This part does a good job of balancing low supply current, low voltage operation and low noise. Since it is a standard op amp, you will need to drive a transformer to create a balanced signal from the single-ended output…
Hi Kumar,
Your equation for Cin looks inline with that used in the evaluation software, it should be ok. Cref is the internal reference capacitance. I have attached an application note that has some detail on this parameter (page 2) which should be true…
