Notes:
1. Mute off and buffer in assume 0.5 V.
2. Mute off and buffer in assume 1/2 VCC V.
3. Represents the interoutput difference.
4. Voltage relative to ground (source) when an 8 Ω load is connected between bridge amplifier outputs.
5. Voltage relative to ground (sink) when an 8 Ω load is connected between bridge amplifier outputs.
Thus, muting is activated when high, and the amplifier outputs 5 and 6 are off.

1. For ICC1 and 2, measure the inflow current on the VCC pin.
2. For VOF1 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).
3. For IB, measure the voltage across the 100 kΩ resistor (IB = V/100 kΩ).
4. For VO1 and 2, measure each output voltage at input voltages 1.75 V and 5.75 V, respectively.
5. VMUTE is the mute pin (pin 15) voltage when the output goes off.
6. IMUTE is the mute pin (pin 15) inflow current when the output goes off.
7. 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 VO/VIN dB.
