#1 Ultra low noise Baxandall volume control...

Post by jack »

For various reasons I'm making some of these...

Any interest in an active ultra-low-noise genuine log/audio-law taper volume control? I'm playing with a setup based on a TI app note which has an interesting take on the classic Peter Baxandall Wireless World article of jonks ago.

I may do PCBs of this if folk are interested - The measured stats are THD+N @ 1khz of 0.0005%, gain deviation from true log of +/- 1.5dB, "off" gain of -103dB
