| Jun 14, 2022 at 12:09 | comment | added | rdtsc | Note that the schematics read "* multiple decoupling caps, as needed". You might get away with it as drawn, but I'd suggest adding (the pads at least) for 0.1µF caps near each TL072 + and - pin and ground. That way, if it is built and squeals badly or generates high-frequency oscillations, just add the caps. | |
