Notes:
1. Mute off and buffer in assume 1/2 VCC V.
2. Mute off and buffer in assume 0.5 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.
6. Muting is activated when high, and the amplifier outputs 3 and 4 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 3 and 4 (amplifiers 1 and 2), pins 27 and 28 (amplifiers 7 and 8), pins 12
and 13 (amplifiers 3 and 4), and pins 18 and 19 (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. VM is the mute pin (pin 7) voltage when the output goes off.
6. IM is the mute pin (pin 7) inflow current when the output goes off.
7. For VG, measure the voltage between pins 3 and 4 (amplifiers 1 and 2), pins 27 and 28 (amplifiers 7 and 8), pins 12 and 13
(amplifiers 3 and 4), and pins 18 and 19 (amplifiers 5 and 6) at f = 1 kHz, and use the following formula:
VG = 20 log VO/V1 dB.
