    I made a function generator using IC 8038. The Square wave and triangle wave output seems to be fine. but the Sine Wave looks pretty distorted( As in the video linked) or the zero crossing is not symmetrical. Can anybody suggest a solution? Thankyou

    Which 8038 are you using? ICL8038 (bipolar) or MAX8038 (CMOS)?
