I am miniaturizing everything. And just experimenting. I measured my boards with these vs the electrolytics i was using. I can’t measure a difference and of course with the OPA1642 I’m already 100dB in the weeds for THD to begin with. ?I’ve laid out a single board with two channels audio and a hex inverter for bias. My next goal is for three or more. Can you say single PCB LDC native B format ambisonic microphone??
Best Regards,
Jules Ryckebusch?

I am trying to get away from Electrolytics
What is your motivation? If it's reliability,
solid polymer aluminum electrolytic capacitors are a good option, e.g. something like . In short, they won't dry up like regular Al electrolytic ones. Tantalum is also an option, but you should apply 50% voltage derating (e.g. get them rated for 20V if they have 10V across them), and there are ethical regarding tantalum sourcing.
