Published:2011/11/24 2:02:00 Author:Ecco | Keyword: Sound level generator | From:SeekIC

The audio signal frequency generated by the circuit is 1KHz, and its value depends on the three RC network of feedback branch road. Output voltage is about 4.2V when the load resistance is approximately 200Ω , and the output voltage's distortion factor is relative to the amplification factor of the transistors, it generally is between the K = 1 ~ 10%.
