I'm considering using passive filters directly after the outputs of the DACs on the ADAU1328. Is this a bad idea?
I see that the datasheet recommends active filters on the outputs of the DACs.
The expectation for my design is that users will be plugging this into devices with high-impedance inputs, so I'm assuming this would be okay. (?)
Also, I couldn't find the output impedance of the DAC's in the datasheet. Does anyone know about what that would be?
Any thoughts would be greatly appreciated.
