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 Brt or Sub Brt 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.Voltagr 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.
4) Increase the input signal(SG2) at Input2 amplitude gradually, starting from 700mVp-p. Measure
the amplitude of the input signal when the output signal starts becoming distorted.
5) 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:
VOUT
GV = 20 LOG
0.7
(dB)
6) Relative maximum gain GV is calculated by the equation below:
GV = VOUT(2) / VOUT(5), VOUT(5) / VOUT(9), VOUT(9) / VOUT(2)
7) Measuring the amplitude output at OUT(2,5,9). The measured value is called VOUT(2,5,9).
VOUT
VC1=20 LOG
0.7
(dB)
8) Measuring condition and procedure are the same as described in Note7.
9) Measuring condition and procedure are the same as described in Note7.
10) Measuring condition and procedure are the same as described in Note7.
11) Measuring condition and procedure are the same as described in Note7.
12) Measuring condition and procedure are the same as described in Note7.
13) Measuring condition and procedure are the same as described in Note7.
