Dear Komrades,
There seems to be some cross-over distortion present at the output from my 741 at very low frequencies ( 6Hz ). Basically I have a simple integrator circuit with a 10uF input capacitor and a 260Ω feedback resistor. The crossover distortion was very bad when I used smaller capacitor and larger feedback resistor. With larger cap and smaller resistor the distortion is barely noticeable but it is still there. I suspect that the poorly designed class AB amplifier inside the 741 is the cause. I would like to know what I could do to eliminate this problem.
Thanks
