Low_frequency_precision_RC_oscillator
This circuit shows a precision RC oscillator, where the frequency is determined by the equation 0.72/(R1C1). The circuit is particularly useful for frequencies below 3 kHz. For a bipolar ±5-V output swing, refer the ground connection to -5 V. Linear Technology Corporation, Linear Appications Handbook, 1990, p. AN20-11.
