M61303FP
IIC BUS controled 3channel video pre-amplifier for LCD display monitor.
1) Measuring conditions are as listed in supplementary Table.
Measured with a current meter at test point IA.
2) Decrease Main Bat or Sub Bat gradually, and measure the voltage when the bottom of
waveform output is distorted. The voltage is called VOL.
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
(V) VOH
Waveform output
VOL
0.0
3)
Increase the input signal(SG2) at Input1 amplitude gradually, starting from 700mVp-p.
Measure the amplitude of the input signal when the output signal starts becoming distorted.
Increase the input signal(SG2) at Input amplitude gradually, starting from 700mVp-p.
Measure the amplitude of the input signal when the output signal starts becoming distorted.
Input SG1, and read the amplitude output at OUT(2,5,9). The amplitude is
called VOUT(2,5,9).Maximum gain GV is calculated by the equation below:
GV = 20 LOG

Relative maximum gain
GV is calculated by the equation below:
GV = VOUT(2) / VOUT(5), VOUT(5) / VOUT(9), VOUT(9) / VOUT(2)
