• Reduces high-frequency noise.
• DC current suppression. A reduction in reactance is effective because of increases in capacitor
• Biases the input pin to zero.
• Effects V
• Due to differential input, input resistance is more or less determined by this resistance value.
• VG settings are obtained using R
• Low-frequency cutoff frequency settings are obtained using R
When changing the VG setting, you should change R
frequency setting. When the VG setting is changed using R
