Hi!
Sorry for being a complete newbie, my question will probably be totally amateurish. I'm building a digital-output preamp based on the PGA2500 and PCM4204. I would need to insert an adjustable 12 dB/octave high-pass filter between the preamp and the ADC. I've never done an active differential HPF and couldn't set your filter-desi1gner application to this design either. Do you have any recommendation for how this preamp's output should be filtered? Thanks a lot!
