Description

MODE = H or open: Output reset

MODE = L: No output reset

MODE is pulled up to the VDD1 in the IC.

Select of inversion or no inversion for input data.

POL21: Data inversion or no inversion of Port1.

POL22: Data inversion or no inversion of Port2

POL21, POL22 = H: Data are inverted in the IC.

POL21, POL22 = L: Data are not inverted in the IC.

The driver voltage can be switched by controlling the stationary bias

current of the output amplifier via VSEL.

VSEL = H: VDD2 = 12.5 to (14.0 V) (large bias current)

VSEL = L or open: VDD2 = (14.0 V) to 15.0 V (small bias current)

LPC is pulled down to the VSS1 in the IC.

Normally, set the TEST pin to H or leave open.

This pin is pulled up to VDD1 in the IC.

Input the γ -corrected power supplies from outside by using operational

amplifier. During the gray scale voltage output, be sure to keep the gray

scale level power supply at a constant level. Make sure to maintain the

following relationships.

VDD2 – 0.2 V ≥ V0 > V1 > V2 > V1 > V2 >... ... > V6 > V7 ≥ 0.5 VDD2 + 0.5 V

0.5 VDD2 – 0.5 V ≥ V8 > V9 > V10 > ... ... > V14 > V15 ≥ VSS2 + 0.2 V

2.5 to 3.6 V

12.5 to 15.5 V

Grounding

Grounding

Cautions 1. The power start sequence must be VDD1, logic input, and VDD2 & V0-V15 in that order.

Reverse this sequence to shut down.

2. To stabilize the supply voltage, please be sure to insert a 0.47 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 0.1 µF is also advised between the γ-corrected

power supply terminals (V0, V1, V2,.. ..., V15) and VSS2.
