C is the capacitance of the input capacitor in farads. R is the input impedance of the IC in ohms. If you refer to page 26 of the datasheet, you will find this description: The input feed-forward resistance for the MIC1LP input of the microphone PGA stage has three settings, 10 kΩ, 20 kΩ, and 40 kΩ, which are controlled by writing to page 1 ...

I built a VCA with a that2180 using a 470nF tantalum capacitor and a 20k resistor as audio input. As source I feed an output coming from an Arduino with a opamp which creates a 0-3.2volt output sine. The sine looks fine on a scope. ... Decoupling capacitors are the ones you find on the power supply pins of ICs. Share. Cite. Follow

If the signal source impedance is low like the output of an opamp then the value of the capacitor is calculated by 1 divided by (2 x pi x f x R) where f is the -3dB cutoff frequency and R is the input impedance that the capacitor is feeding. We do not know the input impedance of each pad, it might be the 3900 ohms that is shown.
Coupling Capacitors

2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used.

TYPES OF DECOUPLING CAPACITORS Figure 5 shows the various types of popular capacitors suitable for decoupling. The electrolytic family provides an excellent, cost effective low-frequency filter component because of the wide range of values, a high capacitance-to-volume ratio, and a broad range of working voltages. It
