Represents the interoutput difference.
Voltage relative to ground (source) when an 8
load is connected between bridge amplifier outputs.
Voltage relative to ground (sink) when an 8
load is connected between bridge amplifier outputs.
Thus, muting is activated when high, and the amplifier outputs 5 and 6 are off.

For I
CC
1 and 2, measure the inflow current on the V
CC
pin.
For V
OF
1 and 2, measure the voltage between pins 5 and 6 (amplifiers 1 and 2), pins 25 and 26 (amplifiers 7 and 8), pins 10
and 11 (amplifiers 3 and 4), and pins 20 and 21 (amplifiers 5 and 6).
For I
B
, measure the voltage across the 100 k
resistor (I
B
= V/100 k
).
For V
O
1 and 2, measure each output voltage at input voltages 1.75 V and 5.75 V, respectively.
V
MUTE
is the mute pin (pin 15) voltage when the output goes off.
I
MUTE
is the mute pin (pin 15) inflow current when the output goes off.
For VG, measure the voltage between pins 5 and 6 (amplifiers 1 and 2), pins 25 and 26 (amplifiers 7 and 8), pins 10 and 11
(amplifiers 3 and 4), and pins 20 and 21 (amplifiers 5 and 6) at f = 1 kHz, and use the following formula:
VG = 20 log V
