R
IN
Input resistors that set the closed loop gain in conjunction with a fixed internal
feedback resistor (Gain = R

/R
IN
, where R

= 50k
Ω
).
C
IN
Input coupling capacitors that block the DC voltage at the amplifier input
terminal. Thanks to common mode feedback, these input capacitors are
optional. However, if they are added, they form with R
IN
a 1st order high pass
filter with -3dB cut-off frequency (f

)).
C
S
Supply bypass capacitors that provides power supply filtering.
C
B
Bypass pin capacitor that provides half supply filtering.
