Rch Analog Input Pin (LDIF bit =“0” : Single-ended Input)
Negative Line Input Pin (LDIF bit =“1” : Full-differential Input )
Connected to the VSS1 pin with a capacitor for mute time constant.
Normally connected to the VSS1 pin with a 2.2μF electrolytic capacitor.
When “L”, the AK4372 is in power-down mode and is held in reset.
The AK4372 must be reset once upon power-up.
This pin must be connected to VSS2 with one resistor and one capacitor in series.
