AN8001FHK
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 V_CC − 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
