Functional Description
C
IN
This is the input coupling capacitor. It blocks the DC voltage and couples the input signal to the amplifier’s
input terminals. C
IN
also creates a highpass filter with the internal resistor R

).
This is the supply bypass capacitor. It filters the supply voltage applied to the V
DD
pin and helps maintain
the LM4856’s PSRR.
This is the BYPASS pin capacitor. It filters the V
DD
/ 2 voltage and helps maintain the LM4856’s PSRR.
