Found in a 90s Electronic Design, this circuit can generate sinusoidal signals from 0.1 Hz to 25 kHz with low distortion using a MA292 from Maxim.
The frequency of the signal produced by this circuit depends on the temperature of the diode used...
The presence of a pulse at the CTRL input produces an audio signal of duration determined by the...
We found this circuit in documentation from the 1980s. The integrated circuit used is uncommon today,...
