The sine wave signal generator is often used in test for audio equipment.Hereby,the sine wave signal generator composed of a double op-amp integrated circuit is introduced.This generator has simple circuit,small total harmonic distortion ,supply and the frequency coverage is 76Hz～16kHz.And it uses uses single power supply. The picture 1 is sine wave signal generator circuit.This circuit is composed of bridge T oscillating circuit,buffer amplifier, neutral voltage generator circuit.The picture's left is oscillating circuit.There is a bridge T circuit between the integrated amp's ① pin and② pin(reversed-phase input terminal) and oscillation frequency is altered via altering bridge T circuit's reference.
