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, V8 and V12 are always set to the

same 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 SW A is set to b.

Vomax Output dynamic range

Voltage V16 is varied as described below:

1. Increase V16 gradually while inputting SG6 to pin 11 (7 or 3).

Measure the voltage when the top of the waveform output at

T.P21 (25 or 29) is distorted. The voltage is called VTR1 (VTG1 or

VTB1). Next, decrease V16 gradually, and measure the voltage

when the bottom of the waveform output at T.P29 (25 or 21) is

distorted. The voltage is called VTR2 (VTG2 or VTB2).

(V)

3. After setting VTR (VTG or VTB), increase the SG6 amplitude

gradually, starting from 700mV. Measure the amplitude when the

top and bottom of the waveform output at T.P21 (25 or 29) starts

becoming distorted synchronously.

Vimax Maximum input

Measuring conditions are the same as those used above, except

that the setting of V14 is changed to 2.5V as specified in

Supplementary Table. Increase the input signal amplitude gradually,

starting from 700mVP-P. Measure the amplitude when the output

signal starts becoming distorted.

Gv Maximum gain

∆Gv Relative maximum gain

1. Input SG6 to pin 11 (7 or 3), and read the amplitude at output

T.P21 (25 or 29). The amplitude is called VOR1 (VOG1 or VOB1) .

2. Maximum gain GV is calculated by the equation below:

VOR1 (VOG1, VOB1) [VP-P]

GV=20LOG

0.7

[VP-P]

3. Relative maximum gain ∆G is calculated by the equation below:

∆GV=VOR1/VOG1, VOG1/VOB1, VOB1/VOR1

5.0

0.0

Waveform Output at T.P21

(Identical to output at T.P25 and T.P29.)

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.P21; VTG1, at T.P25, and VTB, at T.P29.

VCR1 Contrast control characteristics (typical)

∆VCR1 Contrast control relative characteristics (typical)

1. Measuring conditions are as given in Supplementary Table.

The setting of V14 is changed to 4V.

2. Measure the amplitude output at T.P21 (25 or 29). The measured

value is called VOR2 (VOG2 or VOB2).

3. Contrast control characteristics VCR1 and relative characteristics

∆VCR1 are calculated, respectively, by the equations below:

VOR2 (VOG2, VOB2) [VP-P]

VCR1=20LOG

[VP-P]

∆VCR1=VOR2/VOG2, VOG2/VOB2, VOB2/VOR2
