ELECTRICAL CHARACTERISTICS TEST METHOD
1. Because a description of signal input pin and pulse input pin
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
voltage, therefore only V4 is referred to in Supplementary Table.
2. Increase V19 gradually, and measure the voltage when the top
of the waveform output at T.P25 (30 or 35) is distorted. The
voltage is called VOHR (VOHG or VOHB).
3. Voltage VOMAX is calculated by the equation below:
VOMAX=VOHR (VOHG, VOHB)-VOLR (VOLG, VOLB)
(V)
ICC Circuit current
Measuring conditions are as listed in Supplementary Table.
Measured with an ammeter At test point A when SWA is set to b.
5.0
Vomax Output dynamic range
Voltage V19 is varied as described below:
1. Decrease V19 gradually while inputting SG5 to pin 13 (8 or 3).
Measure the voltage when the bottom of the waveform output at
0.0
T.P25 (30 or 35) is distorted. The voltage is called VOLR (VOLG or
VOLB).
Waveform Output at T.P25
(Identical to output at T.P30 and T.P35.)
