Sine wave oscillator circuit



This circuit uses a quad channel op amp with ±2.5-V supplies to generate a 10-kHz, low-distortion sine wave. The amplifiers buffer each RC filter stage, which yields a low-distortion output.
  • IAC specifications:
    • AC Gain = 8 V/V
    • f_oscillation = 10 kHz
  • Supply:
