This circuit can function as an output shield for microcontrollers, being compatible with TTL logic. The frequency is adjusted in the trimpot. TTL power is 5 V.
We find this circuit in the 80's own component manual itself. The characteristics of the circuit...
We found this amplifier with high input impedance and low capacitance, using FET, in a...
This circuit was obtained in a 1979 magazine, but it can be easily assembled today, as the...
