Description
− Input the γ -corrected power supplies from outside by using operational amplifier.
Make sure to maintain the following relationships. During the gray scale voltage
output, be sure to keep the gray scale level power supply at a constant level.
VDD2 –0.2 V ≥ V0 > V1 > V2 > V3 > V4 > V5 > V6 > V7 ≥ 0.5 V DD2
0.5 V DD2 –0.3 ≥ V8 > V9 > V10 > V11 > V12> V13 > V14 > V15 ≥ VSS2 +0.2 V
− 3.3 V ± 0.3 V
− 9.0 V ± 0.5 V

Cautions
1.The power start sequence must be VDD1, logic input, and VDD2 & V0 to V15 in that order.
Reverse this sequence to shut down (Simulaneous power application to VDD2 and V0 to V15 is
possible.).
2.To stabilize the supply voltage, please be sure to insert a 0.1 µF bypass capacitor between
VDD1-VSS1 and VDD2-VSS2. Furthermore, for increased precision of the D/A converter, insertion of a
bypass capacitor of about 0.01 µF is also advised between the γ -corrected power supply
terminals (V0, V1, V2, ∙∙∙, V15) and VSS2.
