ELECTRICAL CHARACTERISTICS TEST METHOD
ICC1 Circuit current1
Measuring conditions are as listed in supplementary Table.
Mesured with a current meter at test point IA.
CC2 Circuit current2
I
Measureing conditions are as listed in supplemtary Table.
Measured with a current meter at test point IB.
Vomax Output dynamic range
Decrease V30 gradually, and measure the voltage when the bottom
of waveform output is distorted. The voltage is called VCL.
Next, increase V30 gradually, and measure the voltage when the
top of waveform output is distorted. The voltage is called VOH.
Voltage Vomax is calculated by the equation below:
Vomax = VOH-VOL

Vimax Maximum input
Increase the input signal (SG2) amplitude gradually, starting from
700mV
P-P. Measure the amplitude of the input signal when the
output signal starts becoming distorted.
Gv Maximum gain
Input SG1, and read the amplitude output at OUT (29, 32, 35). The
amplitude is called VOUT (29, 32, 35). Maximum gain G
calculated by the equation below:
GV=20Log (dB)
