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 −0.1 V ≥ V0 > V1 > V2 > V3 > V4 ≥ 0.5 V DD2

0.5 V DD2 ≥ V5 > V6 > V7 > V8 > V9 ≥ VSS2 +0.1 V

2.3 to 3.6 V

8.0 to 9.0 V

Grounding

Grounding

Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0 to V9 in that order. Reverse

this sequence to shut down.

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 recommended between the γ -corrected power supply

terminals (V0, V1, V2, ···, V9) and VSS2.
