Gradation voltage generation IC

for liquid crystal display

s Overview

The AN8001FHK is a gradation voltage generation

IC for liquid crystal displays and designed for 64-grada-

tion LCDs. It is incorporating an 1.23 V reference volt-

age circuit, 10 gradation output buffer amplifier circuits,

and a COM amplifier circuit.

s Features

• Incorporating a high precision reference voltage source :

1.23 V (typ.)

• Wide dynamic range of buffer amplifiers and it is pos-

sible to provide an output from VCC − 0.2 V (the high-

est stage) to GND + 0.2 V (the lowest stage).

• Large COM-amplifier drive current : ±100 mA (max.)

s Applications

• Gradation power supply source for LCDs
