Connect RIP pin to right channel input PGA
amplifier positive terminal.
0 = RIP not connected to input PGA
1 = right channel input PGA amplifier positive
terminal connected to RIP (constant input
impedance)

Connect LIN pin to left channel input PGA
negative terminal.
0=LIN not connected to input PGA
1=LIN connected to input PGA amplifier
negative terminal.
Connect LIP pin to left channel input PGA
amplifier positive terminal.
0 = LIP not connected to input PGA
1 = input PGA amplifier positive terminal
connected to LIP (constant input impedance)
INPPGAVOLL and INPPGAVOLR volume do
not update until a 1 is written to
INPPGAUPDATE (in reg 45 or 46)
Left channel input PGA zero cross enable:
0=Update gain when gain register changes
1=Update gain on 1
register write.
Mute control for left channel input PGA:
0=Input PGA not muted, normal operation
1=Input PGA muted (and disconnected from the
following input BOOST stage).
Left channel input PGA volume
000000 = -12dB
000001 = -11.25db
