    Description of External Parts

    R1, C1 : Input filter circuit

    • Reduces high-frequency noise.

    C2 : Input coupling capacitor

    • DC current suppression.

    A reduction in reactance is effective because of increases in capacitor reactance at low frequencies and 1/f noise dependence on signal source resistance which result in output noise worsening.

    R2 : Input bias resistor

    • Biases the input pin to zero.

    • Effects VN stability (refer to NF circuit).

    • Due to differential input, input resistance is more or less determined by this resistance value.

    R4, R5 : NFB circuit (AC NF circuit). Use of resistor with 1% error is suggested.
