Internal conceptual diagram of the LM4863
Note: Components are described in the application diagram above
Ri: The input resistance that sets the closed-loop gain with Rf, and also forms a high-pass filter with Ci, and fC = 1/(2πRiCi).
Ci: Input coupling capacitor, mainly used to isolate the DC voltage at the input of the op amp, but also with the input resistance Ri to form a high-pass filter, fC = 1/(2πRiCi).
Rf: Works with Ri to set the feedback resistance of the closed-loop gain.
Cs: Supply the power bypass capacitor of the power filter, refer to the "Application Information" section to set and select the appropriate bypass capacitor.
CB: VDD /2 refers to the filter capacitor of the voltage Bypass pin. Set and select the appropriate bypass capacitor by referring to the "Application Information" section
