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.
