exceeding the limits would cause clipping in the differential stages, thus a vanishing signal.
scale the control current by the same factor.

Use DMA to initiate dummy transfers so the SPI bus never becomes idle. Trying to tackle #24
Figure out whether the buzz goes away, when putting - [ ] the main board or - [ ] the voice board or - [ ] both into a metallic...
The filter overlays the filtered signal with a nasty 1kHz signal. The SPI dacs update with 1kHz update rate. Changing this changes the hum. Since SPICLK is running at 5MHz,...
Leaking occurs even with the signal *not* being routed into the transistor's base terminal oO? Leaking is stronger when a useless film capacitor is connected to the signal on the...
