1_kHz_WIEN_BRIDGE
Simple circuit uses only one section of LM324 quad opamp having true differential inputs. Supply voltage range is 3-32 V. Reference voltage is half of supply voltage.Values of R and C determine frequency accord-ing to equation f = 1/6.28RC. For 16K and 0.01 μF, frequency is 1 kHz. Diode types are not criticaL- Quad Low Power Operational Amplifiers, Motorola, Phoenix, AZ, 1978, DS 9339 R1.
