Components
Functional description
Rpu1, Rpu2
Rpd1, Rpd2
Pair of pull-up (Rpu1, Rpu2) or pull down (Rpd1, Rpd2) resistors that are
connected to the digital volume control pins
UP/DVC and DOWN/DVC.
CIN
Input coupling capacitors that block the DC voltage at the amplifier input
terminal. They form together with the amplifier’s differential input impedance
ZIN a first order high pass filter with a -3dB cut-off frequency
(fcut-off = 1 / (2 x π x ZIN x CIN)).
CS
Supply bypass capacitor that provides power supply filtering.
CB
Bypass pin capacitor that provides half supply filtering.
