ELECTRICAL CHARACTERISTICS TEST METHOD
ICC1 Circuit current1
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IA.
ICC2 Circuit current2
Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IB.
Vomax Output dynamic range
Decrease V1 gradually, and measure the voltage when the
waveform output is distorted. The voltage is called VOL.
Next, increase V1 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

Gv Maximum gain
Input SG1, and read the amplitude output at OUT (24, 28, 31). The
amplitude is called VOUT (24, 28, 31). Maximum gain GV is
calculated by the equation below:
∆Gv Relative maximum gain
Relative maximum gain DGV is calculated by the equation bellow:
∆GV= VOUT (24)/VOUT (28),
VC1 Main contrast control characteristics1
Measuring the amplitude output at OUT (24, 28, 31). The
measured value is called VOUT (24, 28, 31). Main contrast control
characterics VC1 is calculated by the equation bellow:
∆VC1 Main contrast control relative characteristics1
Relative characteristics ∆VC1 is calculated by the equation bellow:
∆VC1=VOUT (24)/VOUT (28),
