ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin
(V)
switch numbers is already given in Supplementary Table, only
external power supply switch numbers are included in the notes
below.
Sub contrast voltages V4, V9 and V14 are always set to the same
5.0
voltage, therefore only V4 is referred to in Supplementary Table.
ICC Circuit current
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SW1 is set to a.
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Increase V19 gradually while inputting SG6 to pin 13 (8 or 3).
Measure the voltage when the top of the waveform output at
T.P25 (30 or 35) is distorted. The voltage is called VTR1 (VTG1 or
VTB1). Next, decrease V19 gradually, and measure the voltage
when the bottom of the waveform output at T.P35 (30 or 25) is
distorted. The voltage is called VTR2 (VTG2 or VTB2).
0.0
Waveform Output at T.P25
(Identical to output at T.P30 and T.P35.)
2. Voltage VT (VTR, VTG and VTB) is calculated by the equation
below:
VTR (VTG, VTB)= VTR1 (VTG1, VTB1) + VTR2 (VTG1, VTB1)
2
Use relevant voltages, depending on the pin at which the
waveform is output; specifically, use VTR1 when it is output at
T.P25; VTG1, at T.P30, and VTB, at T.P35.
