OUTPUT COUPLING CAPACITOR, C(C)
In a typical single-supply, single-ended (SE) configur- ation, an output coupling capacitor (C(C)) is required to block the dc bias at the output of the amplifier, thus preventing dc currents in the load. As with the input coupling capacitor, the output coupling capacitor and impedance of the load form a high-pass filter governed by Equation 7.

10,000 Ω | 68 µ F | 0.23 Hz |
47,000 Ω | 68 µ F | 0.05 Hz |
