1. For ICC1 to 4, measure the circuit current.
2. For VOF1 and 2, measure the voltage between pins 11 and 20 and the voltage between pins 5 and 26.
3. For VBIO, measure the voltage between pins 7 and 6.
4. For IB, measure the voltage across the 100 kresistor.
5. For VO, measure the voltage on pins 11, 20, 5 and 26 by switching the input pin voltage to 0.5 V and 4.5 V, respectively.
6. For VOD, measure the voltage between pins 11 and 20 and the voltage between pins 5 and 26.
7. For VG, measure the voltage on pins 11, 20, 5 and 26 at f = 1 kHz, and use the following formula:
VG = 20 log VO/V1 dB.
8. VM is the mute voltage when the mute voltage is varied and the output is turned off.
