Input coupling capacitor • Used to block DC current. When the reactance of the capacitor increases at low frequencies, the dependence of 1/f noise on signal source resistance causes the output noise to worsen. It is better to decrease the reactance. R2: Input bias resistor • Used to bias the input pin to zero. • Affects VN stability. (See NF circuit.) • Because of differential input, this resistor fixes the input resistance practically. NFB circuit (AC NF circuit). It is desirable that the error of the resistor value is 1% or less.
