ELECTRICAL CHARACTERISTICS TEST METHOD

ICC1 Circuit current1

Measuring conditions are as listed in supplementary Table.
Mesured with a current meter at test point IA.

ICC2 Circuit current2

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 GV is
calculated by the equation below:

GV=20Log (dB)

VOUT

∆Gv Relative maximum gain

Relative maximum gain ∆G
∆G

V is calculated by the equation bellow:

V= VOUT (29)/VOUT (32),

VOUT (32)/VOUT (35),
VOUT (35)/VOUT (29)
