Output frequency: 20 HZ -20 KHZ. Output amplitude: 2 V.It is simple, but has excellent performance and will meet the requirement of DIY acoustic equipment. Principle of the circuit: Operational amplifier CA3140 works as the major amplifier, 100 K potentiometer and phase shifting capacitance compose phase shift, positive feedback and frequency-selective network. 1 K potentiometer and thermistor constitute a negative feedback amplitude-stabilized circuit. Audio signal is output via the follower.
