AD7746 / AD8515 conformal coating

FireFox007 on Sep 10, 2014

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

Hello Chris,

There shouldn't be an issue using conformal coating on the AD7746. Just be aware of the placement of traces to and from the EXCx pins and the CINx pins and check that the coating doesn't increase the base capacitance of your system.
