Function

72 AGND2

GND Audio signal control Mic amp ground pin.

During Mono Sel. R Stereo selection, a signal that has IS IN A (L)

or B (L) or IS IN C (L) or IS IN D (L) added is output. During

73 Pre Out B (L) Output Audio signal control Mono Sel. R Mono selection, a signal that is a mixture of a signal

with (L) input added and then lowered 9dB and a signal that with

(R) input added and lowered 9dB. (See Figure B)

74 Pre Out A (L) Output

A signal that has IS IN A (R) or B (R) or IS IN C (R) or

Audio signal control

IS IN D (R) added is output.

75 Pre Out (L) Output

A signal that has IS IN A (R) or B (R) or IS IN C (R)

Audio signal control

added is output.

76

AVCC

Audio signal control Audio signal control VCC pin.

77 IS IN D (L)

Input

1 of 4 amp inputs that is output to Pre Out A (R) or Pre

Audio signal control

Out B (R), (L).

78 IS IN C (L)

Input

1 of 4 amp inputs that is output to Line Out (R) or Pre

Audio signal control

Out A (R), Pre Out B (R), (L).

79 IS IN B (L)

Input

1 of 4 amp inputs that is output to Line Out (R) or Pre

Audio signal control

Out A (R), Pre Out B (R), (L).

80 IS IN A (L)

Input

1 of 4 amp inputs that is output to Line Out (R) or Pre

Audio signal control

Out A (R), Pre Out B (R), (L).

*1 VD power supply and VP power supply must have the same potential.

*2 In order to avoid the effects of SP, HP amp interference between L and R, and interference between SP

and HP amps on separation characteristics, the wiring connected to this pin should have the same

impedance as other Vcc lines (especially lines with large current). (This is not a problem when Vcc1 and

Vcc2 lines are bundled.)

*3 In order to avoid the effects of SP, HP amp interference between L and R, and interference between SP

and HP amps on separation characteristics, the wiring connected to this pin should have the same

impedance as other ground lines (especially lines with large current). (This is not a problem when GND1

and GND2 lines are bundled.)

*4 The maximum voltage that can be impressed on IS IN E Vol. pin is 2.0V.

*5 The maximum voltage that can be impressed on SP Vol. pin is 2.0V.

*6 The maximum voltage that can be impressed on HP Vol. pin is 2.0V.
